Personally, 3MB images do not bother me ( too much ). What I don't like is:
- sigs that look like a normal message
- sigs that take too much space horizontaly and break the page layout in the process
- sigs that take too long to load ( server down, slow server ... ) and cause the whole page to look as if it didn't finish loading
I suggest that sigs shall be limite to 128 bytes total, only one line and that [img] is completly ignored
