Hi dnj12006,
For bigger pictures you can try using a Print Screen pogram such as YASF
click here or Gadwins Print Screen
click here , both are free. These pics will then need to be resized to the maximum of 600x600 for contests using a photo editing program such as Gimp.
I use Photoshop so I can't answer your question on how to cut and paste using Gimp but you could look in this thread
here on Photo editing. There are tutorials for that there.
