I use photoshop and imageready to make my avitars Z
Most times I make my Avitars from the entries that I've done here.
Currently I am using ReyRey's entry for me when I was chop the chopper, then I animated it (in IR) for Halloween.
this was my last avitar (the pirate one), which was my Egg on Cherry entry with a skull and cross bones added and animated.
If you'd like help creating ones Z let me know, they really aren't that hard to do. Best advice I could give you is before you reduce your size to 70 x 70 sharpen it once or twice.....
