George,

I use the paint program because it is already in windows. It took me a few times to figure it out but once i did it is fairly simple. I'm not a computer guru by a long shot so i'm sure you can do it.

You can Google, "How to resize pictures using paint" and find several ways explained. What i do is just open the photo from an album and downsize the stretch/skew to 50%.
I do this twice to get the right size. I dont know what size this makes the picture, i just know it works for me.

Try playing with it. Maybe you can e-mail yourself pictures to check.
If all else fails i will write down step by step how i do it and send you.
Don't feel bad about having trouble with this. All of us aren't blessed with this computer stuff like Papee is.

Jim
