a picture, just don't know how to resize it to that. making it into pixels/
like; 640 x 800 I don't even know if I'm asking the right question! help if you can! Thanks

I have the later version so I'm not exactly sure if they are the same.

Very 1st thing to do: Make a copy of your picture and use that. Make the original read-only.

Step 1: first thing to do is to crop the picture so it is square. To crop it you should be able to select Format - Crop - Canvas from the main menu. At this point, select a square area (pixels don't matter here - just make sure it is square and everything you want in the picture is there).

Step 2: select Format - Format Image from the main menu. In my version, there are three option buttons. Change the size under image size to 10"x10" and then click on the Image option button. Then change the Resolution to 200 Pixels per inch.

I hope this helps.
