Did you know it's possible to embed images in posts without providing an external URL? For example: base64 encoded image

base64 encoded image

Not sure if it works in internet explorer, but it works in all other browsers. Does it work for you?

It's actually very useful when you want to send html mail since most clients block external images.

Doesn't work in IE7 for me, but it does show up in Opera. Interesting little trick.

Shows up in Netscape 8. It does not show up in IE 7 though..

It works in Opera, Firefox/Mozilla, and Konqueror.

Yeah, fine in Firefox 2 - but that's weird. I'm not sure I understand what you just did.

//edit. Or maybe I do, and that's just plain cool.

What happens if you change something?

Huh, that's pretty cool. [grin]

Works in Opera on the Mac too. Wonder if you could make an exploit out of it.

Yeah, there have been a few exploits in the past that take advantage of the data://base64 thing. Useful but deadly! :o
