Avatars = bad quality

[Trinny]

I've noticed that many of the avatars I want to use has bad quality when I use them here while they look perfectly fine when I use them in other forums.
Why is that?

are you hosting them on another site or are you uploading them from your comp?

I'm uploading them from my computer.

i think it's ok to use your own avatar from your computer, still we can follow the rules by simply using our own customized avatar without putting porn..right?
