How do you do this? I keep trying, but it say I need to be between 0 and 21. No matter what I put in as a size, it gives me the same message. What am I doing wrong?
Thanx
That is 0 and 21kb or file size. A 100x100 image with only blue has a smaller file size than a 100x100 image with multiple colors... it gets more complex after that, but essentially it is the 3rd dimension of size, the actual file size.
Judging from your avatar you've got it figured out.
