I think I'm missing a step, Theresa . . . do I have to download them to my hard drive first?
If I go to one of those sites and right click to get the little pop-up, I can click on copy, but when I come back here and right click again, the little pop-up doesn't have any of the possibilities highlighted so I can't paste the smilie anywhere. It just disappears while in transit.
Maybe I'll try to play around with them a little more tomorrow.
