I don't think abuse is a strong reason to reject this proposal, given that we've already been allowing images in signatures, and youtube embedding in topics. However, I would rank this feature request lower in my list of priorities..

I've made a "youtubesmall" tag, for you to use in your signature. For a start we're limiting it to one per sig. All other signature rules continue to apply.

Dinner time, kthxbye.

No it doesn't, as we don't do autoload embedding. A 2-3KB thumbnail is loaded, that's it.

What OS? And is it 32 or 64-bit?

I use FF3 (Linux/64 and XP/32) and haven't encountered the problems you mention. If someone else reports the same problem or if you can replicate your problem to another computer, I'll have a look. Otherwise I think it's an idiosyncrasy in your setup.

toby.c13: can't be done ordinarily. type the lyrics in MS paint and save as a PNG.

firedauz: thanks, scheduled for fixing One Day In The Future.

Uh thanks.... for nothing.

I think youtube changed their player to show black bars instead of white.

Anyway, thanks for reminding.. it's fixed now and I've earned the thanks
