It all started with this GIF image I found online: https://media.giphy.com/media/9fbYYzdf6BbQA/giphy.gif
I downloaded it to my computer, which runs Windows 10, put it on my desktop, and edited the file name to change ".gif" to ".jpg." The conversion ended up working fine, and I opened the image saved to my computer in my internet browser, Opera, just to see if it would still animate. It opened a file:// URL, and it showed the jpg normally, animating like a GIF would. So, I decided to see if other people saw the JPG animating like a gif, and on a forum site I am an admin for, I uploaded the image as an attachment to a thread. I made the thread, this was the image file I now had, basically just a normal JPG but animated: s4224.storage.proboards.com/5644224/t/crq4LpxP3rTT6eTORg1o.jpg
When I opened the image in Firefox, and got info on the image, Firefox still thought it was a gif in one area showing the file type, though. Internet Explorer said nothing about it being a GIF when I opened the image in that browser. I then saved the page as a JPG, uploaded it to vgy.me, and still got a .JPG result: vgy.me/dX1KGD.jpg
So, have I created a normal, animated .JPG image? Or is it still just a .GIF file that tricks internet browsers? I remember while I was inspecting the image in Opera that it showed the file/image type as "image/jpeg" as well. Seems to be keeping that metadata!
If you serve a file with a .jpg extension, web servers will normally serve that with a media type of image/jpeg, hence that what will get reported in the browser.
But in practice, image files have very different formats, and it's easy for browsers to inspect the file data itself to decide whether it's a JPG or GIF file and process it accordingly. The process that browsers use for doing this is defined in the MIME Sniffing Standard, which includes the MIME sniffing in an image context algorithm.
So, as Xufox says in their comment, it's still a GIF file regardless of its extension.

"If you copy the file to a computer and then change the extension to .zip, and open the zip file, you will be able to see the separate jpeg and MP4 files inside. This is what you were asking I assume?"

Have this weird case when my images are being found in sources, linked correctly, src url is okay, but still not being displayed. Other images in that same folder are being loaded and displayed just fine, but my new uploaded images are not. I'm using open cart and upload images via ftp. Permissions are fine 644 like the others. I asked other developers in my team and no one has any clue why is that. Guys tried downlaoding and opening the image on their computer and can't even open it, whereas I'm using MAC and can open the same images on my computer without any problems. Images are saved as .jpg from Photoshop. What's the deal here? Here is how it looks in Mozilla:
This can happen because of corrupted image file. Most likely it is the extension problem of the file. Instead of doing save as in Photoshop, try exporting the image through export settings and choose png or jpg format there. It should work fine now, it worked for me.
Just to make sure on this front - Are you uploading them as .JPG or .jpg? If so, the problem may lie there...
If you link to a file that is .jpg and you put .JPG into the code for the link, the link will not work.
Make sure you're not using uppercase JPG as some servers will not read/detect them, and you will not able to see the pictures until you change the extension to lower case jpg.
Also, make sure the color mode, if saving them from Photoshop directly to jpg, is RGB format. If you use any other color mode, it may not display at all. CMYK files for example will not display correctly.
I'm having a weird problem and it's driving me crazy. The problem is that every jpg image is not displayed in IE and Firefox browsers, while displaying properly in Chrome and Opera. What could be the cause of this problem? In IE when trying to open a jpg image into a new tab, shows me a bunch of strange characters instead of showing me the image, in Mozilla it pops in the "Save image" insted of open it.
Thank you in advance!
You got an JPG which uses CMYK instead of RGB encoding, and Firefox/IE choke on such files. You just need to convert the JPGs to RGB colorspace, or in Photoshop you can save image like " Save for web"
The server is sending images with text/plain MIME type. The "strange characters" are the text form of the image bytes.
On a nginx server, add the following to /etc/nginx/mime.types to make sure it serves jpg files as an image.
types {
image/jpeg jpg;
}
For an Apache server, create an .htaccess file in the same directory as the images. Add the line:
AddType image/jpeg .jpg
I found the problematic plugin, it's called "EWWW Image Optimizer" which converts the JPG images to WebP format. They have an alternative rewriting in case the images are served from a CDN which seems to not be working yet.
Thank you for trying to help me!
I have no idea why a simple gif image is not being loaded properly. In the html code I have the usual
<img src="/img/loading.gif" alt="Loading" title="Loading" />
and the file is in that folder. The weird thing is that if I place there /img/logo.png the image is loaded properly.
The filename is correct, I've even copied and pasted it renaming the original files.
PS tested on Firefox 12, Safari 6.0.2 Chrome 23.0.1271.95 (all for Mac)
It was probably a corrupt gif. Your code should work with some other gif. If you really want to get the corrupt gif to work, try opening it in an image editor program and then resave it as gif (or any other format).
Silly question, but what does your gif look like? Is it transparent, or white against a white background?
One possible way to diagnose the problem would be (in Chrome or Firefox), to press F12 to bring up the developer tools and look at your img element to see if the image has loaded in the DOM.
I think the problem was with the gif file, probably somehow broken. I got it from a random resources web site and downloaded from it.
I've tried with a new file got from http://www.ajaxload.info/ now with the code unchanged it works fine.
Edit: the "broken" gif file was working fine elsewhere in the system (e.g. quicklook).
I have done a favicon.ico for a quick client request, redone my cache but in my firefox it seems to show a blank favicon in the navbar, not sure if its my machine or not as tried on a offline native browser and get the same result however amazingly IE on my local seems to show as expected!
I done a 16x16 favicon based on PNG format to withhold the PNG quality of transparency but as i said above on firefox locally it shows nothing - can onlyone with firefox 2+ 3.x to latest 3.6 run a test for me to see if that can see the rugby ball favicon i have created as want to make sure its working off local before i do their other sites favicons! the site is ramrugby[dot]co[dot]uk
Thanks in advance!
It comes up blank for me.
There is no need to create an .ico file in .png format to retain transparency. ICO will already retain transparency.
The best way to create a proper .ico is to download the .ico photoshop plugin, which adds an additional ".ico" image format to your Photoshop "Save As" image format list.
The plugin is free, and you can get it here:
http://www.telegraphics.com.au/svn/icoformat/trunk/dist/README.html
Download that, put it in your Photoshop > Plugins > File Formats folder, and save, then restart Photoshop and you can create icos.
i'm trying to create a newsletter in a single html file, which will be loaded into outlook express and sent out as a mail.
i have like a few images embedded onto the html file but 2 of them cant be loaded for preview in design mode. there is no problem for the rest of the images. those images that cant be loaded has the grey color icon.
the directory for the images are the same. i have copied and pasted the absolute directory for the images that cant load and it doesnt work.
the images loads fine when executed from the html file that was uploaded to the webserver.
edit:
it only loads fine in firefox, and not ie!
i need to get the newsletter out tomorrow, any assistance here?
thanks in advance.
That sounds like a transparent PNG. If you are using an old version of IE, you are out of luck for the HTML email. Try using another type of image (8-bit PNG, PNG with no alpha values, JPEG, GIF). Open the image in your editor and save it as an 8-bit PNG, for example. An 8-bit PNG can only have binary transparency. You may have to redesign the page/email.
