I tried to embed a base64 encoded Java-Applet in my HTML-file.
I thought I could use a data-url like in my example below:
<applet
name="AppletName"
id="AppletId"
code="Applet.class"
archive="data:application/x-jar;base64,UEsDBBQAAAAIAGY/eziUsj5wxAAAABwB...
</applet>
This did not work. In my tests Firefox and Chrome crashed.
I also tried different MIME types.
Any Ideas?
Thanks in advance!
There are a few issues:
The tag applet does not have the correct attribute values
The base64 encoded data URI must be able to be decoded by a browser, not a plugin

The conventional wisdom I keep seeing is that ampersands for user facing text and hrefs and such in HTML need to be encoded so that they don't mess up the parsing of the HTML. I also see conflicting advice that HTML 5 has now loosened the necessity of these conventions so that you can just pass something like
...
and it will render just fine.
I've been seeing that when I write the HTML with the encoded ampersands like
...
, modern browsers like Chrome, Safari, Firefox, treat the encoded string literally. When I click on that href, those browsers will take me to the URL somepage.html?x=1&y=2 instead of the URL somepage.html?x=1&y=2.
This has been breaking the functionality of some external links. Let's say I embed an external link in my website to an audio asset like an MP3 for some on demand music that belongs to some 3rd party provider I don't control. When I put it unencoded like somepage.html?x=1&y=2, the browser takes me to the URL somepage.html?x=1&y=2 and the MP3 downloads just fine. When I put it encoded like somepage.html?x=1&y=2, the browser takes me to the URL somepage.html?x=1&y=2 and the MP3 does not download at all. The website that the link belongs to gives back a blank response.
Why are these browsers ignoring the encoded ampersands and treating the href string literally? Does this mean we really don't need to encode ampersands any more for links? Now it's safe to just put links in hrefs as-is? In that regard, is it possible that nowadays, HTML encoding ampersands can actually be detrimental to the functioning of a website like in the example of the MP3 from some 3rd party provider?
Having issues getting a Tiff image I'm receiving from USPS to render into a base64String and then display successfully using an html image tag.
MY guess at this point is either the image is corrupted in some way that dose not allow it to be converted into correct base64. Or, I am missing something when trying to display the image.
I can "successfully" convert the image to a base64String using the base .Net conversion library and several other online converters. No issues from what I can tell there. But when I go to display the image I'm unable to get it to render.
<img src="data:image/tiff;base64,{myBase64String}" alt="Return Label Image">
The full image source with my base64 string,

Any help or suggestions appreciated.
Your encoding is fine, if I paste it into the box at http://www.freeformatter.com/base64-encoder.html and hit "Decode and Download" it downloads the image. The fiddle works in Safari, but not other browsers. Main issue is that most browsers don't support TIFF.
https://en.wikipedia.org/wiki/Comparison_of_web_browsers#Image_format_support
You will need to change to a different image format, maybe PNG or JPG, before you can use the data URI in all browsers.
Does anyone know of a way to play .h264 in it's raw format in HTML? Tried using the tags, but it says video / mime type not supported.
Annoyingly, I'm not able to convert the files into different format (long story..). Tried the normal google routes, but no luck.
I'm trying to display an .ico within an image element <img> but in Internet Explorer it does not work/show. This is my code:
<img src="images.ico" >
Does anybody how to make it show up in all browsers?
Displaying an ico file in an img tag is not guarenteed to work in all browsers(and i wouldn't recommend it). Convert the ico files to another format if you want to display them on the web.
You can always put the base64 representation of an icon in the src attribute. It will look like this:
<img src="data:image/x-icon;base64,...">
where ... will be the base64 representation.
If you need a tool for conversion from icon to base64, you can use Base64.Guru encoder for example.
Here is the snippet with Google favicon encoded in the base64 representation:

If you ever need to convert an image to base64 by yourself using JavaScript, here are some good examples how to do it: How to convert image into base64 string using javascript.
try to do: embed .swf into html inline using base64 encoding
i read a post somewhere saying this is no longer possible with flash 10+
any hacks or definitive answer?
'data:application/x-shockwave-flash;base64,Q1dTChQHAAB4(cut)9ktAW5/4BvdnQmw=='
does not work anymore
Why, I think if you do that on <object> tag it should work, not sure why would it depend on Player's version, I'd imagine that the SWF is loaded by the browser, not the player.
