I noticed that when you upload a profile picture DNN generates several dimensions of the picture _xs (32 x32) _s (50 x50) _l (64x64). The _l (64x64) is used for the member directory avatar. But when you change the dimensions in the template for example 120 x102 px the image ins't sharp anymore.
How can I change the dimensions and still remain a sharp image?
DNN uses UserProfilePicHandler (profilepic.ashx) but 64 x64 is to small.
