Cat and Star ink drawing (as a png file this time.

The set of eight cat and star ink drawing scans I uploaded earlier don't seem to be showing well. If you click on one you get an inverted version of it. As if the whole thing is black with light white chalk marks. I'm trying to find out why. They are gif files. I know gif files used to do that in certain circumstances but I don't know why. So this image is a png file. Let us hope it works better.
