How to eliminate duplicate image references on model?

[dwigfor]

How can you eliminate duplicate image references on model? Fot instance, in Explorer/o/clips:
body
body1
body2
head
head1
head2

Instead, I would like only:
body
head

I found a model on the internet and it's got like a thousand references to the same image!

You're going to have to go through the shaders and point it to the same clip. Then remove all the extras. Worth noting is that the image CLIP is different than the image SOURCE.
