Would it be possible to get rid of smilies like these; in signatures etc?

Eventually if it isn't possible, wouldn't the standard vB smilies be enough? Or maybe an extra smiley pack, but in the same size as the original ones.

It's kind of annoying IMO that some people use these big-ass GIF's in their signatures because I want to read something but then there's an annoying emoticon playing beneath it.

Ofcourse that's a bit exaggerated but it was the case a few minutes ago. What do you guys/girls think?
