What I do is take a Screen Shot VIA Print Screen (Located inbetween Scroll Lock and Pause/Break normally), open up MSPaint (or any other application), paste the Screen Shot. Use the rectangle cut out tool around the area I want to make a image. Copy that (or cut it). Open a new file, paste. Save.
Upload it to Photobucket or any other website like that.
PM me the image.
I'd like to see some of your work. I see you on the FG forums, so I'm guessing you're pretty creative.
If you want to send the whole file, Go to "Save As" save as anything on your desktop, and then just upload it to a website like Zshare.
