The client doesn't want the photo to be downloaded if it is right clicked on. I explained if someone wants the photo they can get it off the site but he wants to make it a bit more difficult for a novice user to download the image. Hence if you right click you will get the blank 'photo' instead of the actual photo underneath.
Use logic:
Put the image you want to protect as a background image in a <div> or other block level element
Put an <img> that is transparent over that image in the <div>. Make sure it covers the entire image/div
A quick google has thrown this up for me, hope it can help you.
4) Prevent Downloads Using Tables: 'Right clicking' images is a fast shortcut to find, copy, and/or download images. For those that have their own website it is possible to prevent this action by placing images as a background to tables. The code is fairly simple in CSS, using the "background-image:url" style:
<table style="background-image:url('image.jpg');width:Wpx;height:Hpx"><tr><td></td></tr></table>
Another method might be,
5) Javascript Right Click Disable: Another measure to prevent right clicks on images is to use Javascript. These short scripts over-ride browser right clicks. Rather than recreate a script that has been widely published in various forms over the internet, I will leave it to the reader to search google for Javascript Disable Right Click. I will however mention that Javascript is client-side, and scripts such as these can not only effect the usability of a website, but can also readily be disabled by turning Javascript off.
I took the info above from this site --- http://www.naturefocused.com/articles/image-protection.html ---
People can just printscreen the image and put it in paint if they really wanted it though im afraid :(
Thanks,

I have a portfolio site that I used in p5.js, and this ad appears above me. Is there an option to cancel it?
the way is solved this was by hosting the p5 code on my website. This removes the banner completely. However if you want to have more than 1 canvas you should take a look at the link below. To position each canvas where you want use the id selector in css to position it.
https://editor.p5js.org/caminofarol/sketches/r609C2cs
I hope this answers your question.
This is not an "ad", but a banner meant to clearly identify the page as being something hosted on p5js.org. As I mentioned in this answer
A change was recently made to p5js.org that eliminates the banner-less full screen preview of a p5.js sketch created with editor.p5js.org. This change was made because somebody was abusing the site to phish credentials.
For the time being you can still use https://openprocessing.org/ to host sketches such that you can embed them with no banner (however there's no guarantee this won't change in the future). If you want full control of how your sketches look when you embed them on another page I suggest you host the content of your sketch on your own server.
I'm wondering how to replace my social media icons with my own custom images. For example instead of using the typical Facebook Like button or Twitter follow button I would replace it with my own image, while keeping the same functionality.
Websites like BuzzFeed and SuperCompressor are good examples that it can be done. Each has replaced the Facebook Like button with a custom image but the functionality remains the same.
I'm having a hard time finding any information one the web. Can anyone guide me in the right direction?
As the place you will find this image may depend on the plugins and themes you use, you have to find out where the actual image comes from.
To do so, I would suggest that you install a browser such as Chrome that allows you to inspect an element on your page (will open the portion of code displaying the selected item). Once you see where the image comes from, you can either replace the actual image with a custom one if it's on your website's server, or search your website files for this image's URL and replace it with a link to the image of your choice.
I think something like
this http://www.inboundnow.com/apps/facebook-like-button-generator/
might work but the google search for
custom facebook like button for website
has a lot of results
EDIT: Well if you already know how to make a custom image you can follow

This site also has some info
Assuming there is no og:image or link rel img_source, does anyone have any real-world experience or advice on better-than-random techniques to choose an image that best represents a web page?
Update: All answers are good, so upvoted them all and selected one, although it seems there is no great way of doing this. I will experiment with largest picture and screenshot of what it would like on a low-res client. Thanks all!
PS: I'm finding that quite a few pages seem to have og:image or link rel img_source anyway. More than I expected
Taking a screenshot of the website in its smallest possible form, how it would look on a notebook laptop or even a mobile (but not the mobile site version), would be a non-random approach.
Most good web designers will try to make sure users are able to see what the page is about immediately upon loading and include the most important and relevant information 'above the fold' as they say.
Choose the logo of your page as the og:image. That way your brand becomes associated with all your posts, without having to worry about what image best defines each individual page.
For other pages, you cannot control what image they have.
You could investigate how sharer.php works but other than that there is no silver bullet as to choose which image for a web page that has no definable image.
I don't have any experience with Facebook opengraph, but one trick I've used before is to grab favicons of sites I've linked to and use them as link button icons... They're small and are usually always associated with the company name and/or logo, and they're pretty universal across most professional websites. And the usually univeral filename favicon.ico makes it really easy to pick out of the html (or the link attributes if they change the filename).
Might give that a shot if that could be adapted into what you are trying to do. If you find that doesn't look too good, you can try a more "web 2.0" take and check for iPhone/iPad button apple-touch-icon png images (probably only find them on big name sites though)http://developer.apple.com/library/ios/#DOCUMENTATION/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html
I would normally suggest that you simply scrape the page of img tags. However, these days, CSS background images are frequently applied to h1/header/div/a/etc. tags to display logos in place of text.
One possible solution is to grab all elements with 'logo' in their ID/class name:
var l = $('[id*="logo"],[id*="Logo"],[class*="logo"],[class*="Logo"]');
If this is/contains an img tag, chances are you have the site's logo. Otherwise, if it's a div or other such container, you'll need to dig into the child elements' CSS properties to see if they have a background image.
From this you can build a set of candidate images, which when combined with a heuristic based on (for example) image dimensions, should hopefully spit out a logo every time.
I hope this helps you on your way!
Going for the logo is usually the wrong way. Seeing it from a user of your website's point of view I would rather want no image than a logo all the time. This is the same as in Google+ or Facebook links. Only show images when it really does make sense.
However finding the corresponding image may not always be trivial if there is no og:image or rel="image_source" provided.
An article usually has a title which is presented as <h1> or <h2> tag. The nearest image may be the right one. However the nearest may also be a logo so this can go wrong.
I would do that very pragmatic. I would fetch the most likely image first and read the given EXIF data, if this is a real image there are informations provided. If this is just a logo, spacer or some other kind of layout graphic it does not have EXIF data and therefore is not relevant. If the first picture is not the right tough, I would fetch the next one and so on.
Another clue may be the HTML5 <article> tag which usually has the corresponding image to the post nested.
Nevertheless there are several web designer not using standards and their webpage may not be parable nicely.
First time overflowing the stack.
I'm making a website with several html pages that are identical except for the fact that they contain different images that are more or less identical in size - and thats how they are named, by the jpg that they feature.
The pictures look great with the website, but I have a 300 pixel header that pushes them downward > forcing you to scroll down to see the full image. This is built into the shared CSS for all these gallery pages.
I have simple text links below the images that are hard coded to point to the next image in the gallery. (I have a list of the 20 images im displaying). When someone clicks the image, it goes to that page and resets the scroll to the top, which makes the header push the image area down.
Can anyone tell me how to prevent the scroll reset behavior of the new link?
Without using something like jQuery, you could link the pages such that you have an anchor tag like <a name="gallery"></a> above the images on each page and when giving the link to the various pages, append a #gallery to the url such as Next Image. This is duplicated on each page however, and will not produce a robust webpage. You'll want to change things in the future and this will cause problems and further work, so I would consider a dynamic alternative.
Note this won't look as seamless as with jQuery and using AJAX to load in the images when needed. Or better yet, as most JS galleries work, load the images into the page invisible at first and then with JS have them show up on the link click. The benefit of this would be that you could generate the links in JS using the provided images. If the images are large enough that they may cause considerable lag on page load, consider making placeholder images of some sort. In any case, take a look at lightbox 2.
Also, I didn't get the feeling you were using any server side scripting to create this gallery. If the js solution doesn't suit you or you find the added benefit of generating part of the website automatically based on the content need at the time, take a look at using something like PHP, Python, Ruby, etc. If it's just a simple website you're after, a great solution might be Wordpress.
You could have one page and just replace the images?
http://www.quirksmode.org/dom/fir.html
Now of course you change the function to work on a "previous/next" button system, assuming you have a photo gallery of some sort.
Please post more details.
You want your link to look something like this:
<a href="http://www.w3schools.com/html_links.htm#tips">
Visit the Useful Tips Section</a>
and you want to give your image an id="tips" in this case.
Check out this fiddle to see an example. The only difference is that your href will have the rest of the url in there like the code posted above.

i have a image that i don't want it drag-able or selectable so that no drag to other places on the page. how is that done?
If you want your visitors/users to see the resource on your page there is no way to stop them downloading it or saving it.
Possible options:
You can use JavaScript to prevent the context-menu popping up on right-click (related article: http://javascript.about.com/library/blnoright.htm).
You can cover the image with a transparent .png or .gif so that clicking on the image simple returns the transparent image.
But if the user can see the image on the webpage then it's already on their computer.
In reality this is far harder than you may think it will be, I assume you don't want people stealing your images which is a fair enough thing but just remember all the different ways in which someone can get an image from a web site. Your can catch the right click event and stop them at least doing that, but they can always just take a screenshot and save that instead. This is a slippery slope and it always ends the same way, if they really want to steal it, they're going to.
Since the image is just a binary data, and all the data is written on client PC's, for displaying reason it's up to th euser what they'll do with the data. There's no way you can prevent them from saving the picture displayed on a website.
All you might do is make it a little bit harder, by blocking right clicking on image, (displaying alert on right click, or something like this). But if the user really wants to save the picture they will do this anyway.
Why should you do it?
I can suggest a javascript that will able it: http://www.brownielocks.com/stopcopying.html
But every one, even with little experience can view the source and copy it. and even if you block them from viewing the source, they can use wireshark and get the picture directly. Even if you use flash to show the picture one can screen-capture the screen and retrieve the picture.
Put a watermark on the picture and use http://www.tineye.com/ from time to time and search for your picture. If you find others that use your picture - sue them. It is the most effective way.
It is impossible to prevent someone to store an image (or other resources) on their computer as others already have mentioned.
But another trick to make it harder (impossible for inexperienced people I guess) is to use CSS and background images:
<div style='background: url("myimage.gif");'></div>
The image is now on the background of the <div> block and cannot be dragged or right clicked in order to save it.
Using some coding knowledge it is possible to ind out the myimage.gif part, which can be added after the base URL in order download the image and save it. For example if the HTML page is at http://www.example.com/mypage.html the image could be found at http://www.example.com/myimage.gif
As I mentioned it is still possible to save the image, but for inexperienced people it is a lot harder.
Note: In this example the image is just put in the HTML tag, but with proper use of a CSS file, it is even harder to find for inexperienced people.
You cannot prevent a user from saving something from the web to his PC. The nearest thing that comes to my mind is the -moz-user-select CSS property... https://developer.mozilla.org/en/CSS/-moz-user-select
This javascript snippet does exactly what OP asks:
document.addEventListener("dragstart", preventDrag);
function preventDrag(event) {
event.preventDefault();
}
