go to User CP.. user control panel then click on edit profile picture. its got to be no bigger then 100 x 100.. or wait.. that didnt work for me... i see no pic by my name
[hr]
click that.. make it no bigger then 100 x 100 and less then 10k.. u just typed in 100 for height or width and it auto adjust the other to make pic look right. then adjust the quality to lower file size... If you click resize and need to adjust it more, be sure to click on UNDO before trying to make anymore changes in quality.
