argh! I seem to have lost my PNGs. I guess I'll have to start again.

Valerie, one of the problems with the Mac finder is that it can "bottom
out" on file sizes at 4K. If you go to the terminal window and list the
true file information using "ls -l" or some similar command, you'll see
the files are *much* smaller -- some down to 100 bytes or so.
