i use psp.
To cut pictures out, get a picture, go to
http://www.google.com to find them. Then copy the picture. Go to psp, on the work area, right click and paste as new image. Use the lasso tool, use the point to point option. This should be in the tools pallet btw. Then just 'lasso' the portion of your the pic you want. Once you gone around the portion, right click. This should select the portion, right click the selection, copy and paste it to your sig.
Keep practicing, it's hard the first time, but PSP can be as powerfull as ps. I rarely use ps, i'm a psp freak i guess lmao oOo:
