Extract PNG frames

I'm kinda adding something here for two reasons. 1. To bump the thread cause I can't believe no one has any ideas and 2. I may have actually worded the question wrong. When you use Stardocks "AniUtil" to assemble a series of png images for CursorXP. I'm wanting something that can extract those frames back out. Any Takers? Please? Even if you have to lie to me!

I use the crop tool in either PSP or Irfanview - tedious but works

example .png 150x1500 = 10 frames 150x150 put into a png strip
open the strip start cropping out 10 150x150 frames

irfanview is real tedious - crop one at a time whilst reopening the strip to get the new crop

psp on the other hand - select your crop - click the check mark - copy, paste as new image, go back to the cropped, undo, select new crop, click the check mark, copy, paste as new image, etc, etc...etc

Thanks Bichur, I was kind of leaning that way. After doing some thinking (which really hurt by the way) it finally dawned on me that it's not really an animation like a gif or a mng file. Therefore it has a different requirement. I really appreciate you taking the time to think on it and post your thoughts! Thanks, Rad

yeah, once it's in that strip it's like a panoramic - one pic

I find the cropping etc easier (though still tedious) via PSP as opposed to Irfanview - though Irfanview does give me an easier option of selecting the crop size and position (so it will pop up where you want it, if you set the x,y)
