Signature Guidelines: Absolutely NO animated images in signatures

[Tenuke]

Now this is good news. I have been wondering quite a lot why it seems to be allowed for ppl to have signatures that fill about 1/4 of my screen.. And Im using 1900x1200 Resolution..
Is it OK for me to start spamming reports about too big signature images?-)
Seems like every of these old&common
signatures are too big to start with

P.S. This image was first of such signatures what I came past when went to look for an example. Those img's are 489x150. When 350x125 are allowed.
P.P.S. I would think about limiting the size of signature itself too, not just the image sizes. Some ppl have been loving to write some nonsense to their signatures with some super big fonts in bright red, and darn that annoys one easily when those ppl post actively into some thread.
