PDF is one you can't paste into other things like you can image files. At least, not as easily.

I suspect there are quite a few ways to do this. It's what each of us is accustomed to for our particular uses. I use that technique a lot because I do screen captures and save them as smaller image files. There are programs out there like SnagIt that do the same thing, but I've never really needed them since I have all of the Photoshop stuff handy.
