I actually emailed Scott, and he walked me through it. Would have to find his email again.

While I don't want to put down Paint, (if it works and is easier), that's great.

But Adobe Photoshop CS4 is still the standard. A little more complicated, but the above site and other sites can give you the directions.

Oh, you should be able to download a full trial version.
