This is a forum for communicating with words about discgolf, not a gallery for aspiring graphic artists. I think a person can have a unique creative avatar in 80x80, think of it as a challenge.
Andy, you have to be considerate of people who don't have broadband and big, hi-res monitors. I would not like having to wait for someone's avatar to load on my slow dial-up just so I can read about discgolf and I shouldn't have to upgrade my service/equipment just to accommodate someone's desire to be artistic on a discgolf discussion site.
Your original image was 80k and almost 300px wide, no big deal on my big monitor with a fast, cable modem, but when I check the site on my dad's 14inch monitor @ 800x600 with dialup your "unique and creative" avatar takes up HALF the screen and takes several seconds to load. This is the reason the software has max dimensions.
