So, I have this problem. I don't know how to make the image area bigger without making the image itself bigger. In example, I have a picture that is 90px X 100 px. So, I'd want to make it 100px X 100px, so that the image would be the size it was, but there would be more room. I've always done it like that, that I've done new file that is 100px X 100 px, and then copied the original image there, but I think that there's got to be faster way.

I hope you understand this, my english is kinda weird. :D
