This is the fallout from a massive screw-up on my part some years ago. It had something to do with me trying to learn how to deal with non-Xcircuit non-eps source images.
If AAC downloads images from ibiblio periodically, it should have updated to the correct image.
The correct image is the above at ibiblio.
Need to have jrap or an administrator look into this.
There may well be other similarly screw-up (by me) images at AAC
