it says no more than 100 x 100 pixels. Whe I posted 100 x 100 and lowered the quality od save on [photochop as low as I coiuld it still said my phoito was way too bit. My puppy photo is fuzzy and smaller than geezer, tracy or Bradley's photos and theirs are crisper. How do I make a big nice clean avitar that will post? like how many pixels ? How many inches? How high a quality in the save? Is JPEG a good choice or something else?
