I've been trying to make some icons. I'm not doing anything except shrinking the pictures down to around 100x100 pixels. It seems like they look clear in the program I use to shrink them, but then when I upload them as icons, they seem to lose resolution or something. I was saving them as jpg files but these next few are png files. Does that make a difference? When I look at other people's icons, they seem so much crisper. Am I doing something wrong or do I just have a sucky computer?
