Sorry for interfere but maybe it could help you. First, I agree with tamlin that picture is worth a thousand words. Yesterday, I found one free program called
Photoscape. I downloaded it and tried. I usualy work with photoshop CS2, but if you need only to re-touche your old family photos it could help you a lot. It's very friendly to use with lot of good filters. You should certanly give it a try. It's aprox 13 MB. I'm very surprised that such good piece of software can be so good and free
