I notice some of the new style sites aimed at use on mobile devices and tablets allow huge avatars and sigs.
Crazy way to make sites if you ask me.
Give people a smaller screen and present less info at a time ?
Thankfully here there are sensible limits we politely encourage, whereas at Beyond Unreal I make good use of Opera content blocker
BTW. For those that use avatars attached to various services, Gravatar can be convenient.
You can see the full size version of my current avatar http://gravatar.com/drflay
I keep meaning to do a new one with a bottle of rum and without the coke machine
Some of mine are logos for the music side of my life, and again all hand made
The Artist "Dr.Flay" needed a recognisable logo, that could be re-used
and so did the music label "Fishy Business".http://www.last.fm/label/Fishy+Business
