Although you can't copy images to your notes page this way, you can add in a couple of comments on your notes page about an image and even leave several blank lines for a quick sketch. You may find that sketching the important features of certain images is better for learning than merely copying the image and staring at it later.
This type of note-taking is sometimes better done using a simple, fast text editor rather than a big, full-featured word processor. I've placed a little, high-quality text editor called "Tex-Edit" on the Macs in the student lab. It's accessible from the Apple menu. If you use it, just keep your text in "block" style with blank lines separating paragraphs and headings (this little editor doesn't do tabs or other fancy formatting--that's one reason it's so fast). When you paste text into Tex-Edit or a word processor, you may find that there are unwanted "returns" present, causing some lines to end prematurely. In Tex-Edit, you can fix this easily. Just select the text you want to fix (using the mouse) and choose "Modify Selection" from Tex-Edit's Special menu (or press command-m, see below).
Then click the option "Strip CR/LF's" in the Line Endings section of the box that appears (see below).
Finally, click "OK" and your text should be fixed (it's quick--just a selection, menu choice, and two clicks). Don't select lists for fixing like this or you'll squish the lists into a paragraph (in that case, you want the lines to end where they do).
I think you'll find Tex-Edit very convenient for this type of work. Its files are readable as "text-only" by word processors and other text editors such as TeachText. Incidentally, if you would like a copy for your own use, it's freely copyable as shareware (mail $5 to the author if you decide to keep using it at home).
