I'm trying to make a background using PSP 8 for a site and I have no idea how big, like how many pixels, is has to be for it to show up right on the screen. Any ideas?

What is the background going to look like? Depending on that and how it's repeated you may need to make it bigger/smaller

Usually I make it about either 150x150 or 300x300 depending on how many times you want it to repeat.

Thanks, I tried both those sizes and I'm gonna go with 300x300. Thanks again!!!!
