Hey folks,

I'm trying to average a bunch of images in batch process.  Basically, I have

Paint Shop Pro doesn't let you do more than one at a time; ImageMagick
advertises this capability but so far doesn't seem to be able to; and using
GD in perl doesn't quite seem to average images so much as it mangles their
color tables.

Has anyone had any luck with a tool that does this, or am I stuck doing it
one image at a time in PSP?

I used to do a lot of that...  of course, using matlab it's really really
simple...  odd, I tried useing 'convert' from the ImageMagick package and
it seemed to work ok for me...  how's it failing you?
