I used to use PICTURE IT 99 from microsoft. But Microsoft went to VISTA, and I bought in, not realizing that old programs don't work with VISTA. (because it is a SCAM).
Now I am using Corel Draw Paint shop pro. I tried PHOTO SHOP, but My poor old brain went into overload at times. Tripper is good at photo shop.
I had to get the book out with the newer stuff, it does more but some of it you don't need. I highly recomend PICTURE IT 99 for the ease of use. BUT XP is the latest version it works with.
Most all of them require a little book work with.
Just post up some good pictures ( like a straight on side view from level to the door handle), of your victim and ask for a photo shop, some one will jump all over it, if not me.
