Cool !
Somehow, that reminds me how it's possible to insert javascript code in gifs.
Do run this :
Code: [Select]
<html><head>
<img src="microbee.gif">
<script src="microbee.gif">
</script>
</head><body></body></html>

And download this pict.

It should work on Firefox.

This is how it works apparently. https://quadhead.de/storing-javascript-code-in-gif-images/
It shouldn't be harmful, considering you need the ability to inject a <script> tag into the page.

IE6 doesn't even need such a gif to crash while loading a page :P

IE6 crashed much less than the 2005-07 versions of Firefox, though :P (version 1.05 until the end of 2.x). I had to CTRL+Alt+Del every 5 minute or so when using Firefox.

There was also the bug that caused Firefox to use 6 times more resources than Crysis at maxed out settings when a link was broken from time to time. Firefox would just freeze and make the entire computer lag like crazy for about 30 seconds before the Page cannot be found/loaded screen appeared.

Anyway I clicked the first post link in Opera and the tab just said out of memory after freezing for a second. To be honest, I don't like data images because they're hard to share (since the URL is so long and often won't fit in the address bar)
