Wow, thanks, that was fast (years faster than the last post!).
Will give it a look.

Meanwhile, while I posted on a dead-end thread, I wound up finding (and being) "here" - and want to thank Pomeroy too.

It took just a bit of fiddling with preview and iPhoto to get the annotate function in play, and a few minutes to figure out how to size, color, and place the text, but as described, Preview seems to be a decent tool for simple things like placing a Copyright notice on the bottom of a publicly posted photo or info graphic. I actually have enjoyed some of the iPhoto features, especially the easy eye red-out, cropping, straightening, and adjustment tools. For web (other than the "add text" option being dependent on Preview) there are some good tools and features. (I'm using Lion and the latest iLife version - fwiw. In Preview it's a matter of tools/annotate/add text. That's it!)

I use a second photo sorter/editor for Mac (ACDSee Pro) which can do resizing and some other things, but not text overlays. So, it's a way to go for me, thank you much. And for the additional software recommendation too.
