Averaging a set of images?

Hey folks,

I'm trying to average a bunch of images in batch process.  Basically, I have
33 pics, so I average pic 1 against pic 2, then average the result of that
against pic 3, and so on, until I process pic 33.

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?

Cheers,

(...) Did you want pic 33 to have way more weight than pic 1? Unless you do, you need to do the 2 at a time as a bracket instead of linearly if you're using PSP. (average 1 and 2, then 3 and 4.... 31 and 32, 33 and 1-2, 3-4 and 5-6 ... 27-28 and (...) (24 years ago, 22-Mar-01, to lugnet.publish, lugnet.off-topic.geek)
