I was looking and found some but they didn't work. I wanted to know if anybody has any I can get.
Thats probably because your avatar has a bigger size than the one permitted (35K) ;)
There's a problem with linking to avatars hosted on the net, or at least there once was. If you find one that fits the size parameters and still isn't working, try downloading it and getting it off your computer instead.
Or ask the admin.
