So I have a 8300 curve and I use the facebook application to upload a lot of pictures. All my pictures have 72 dpi as bot horizontal and vertical resolutions after I upload them.

A friend of mine who has a palm centro, which only has 1.3MP camera. All the pictures he uploaded have 96 dpi as horizontal and vertical resolution.

I'm just wondering how come the pictures I took with a better camera turn out to have worse quality on facebook?
