Todd, how do you want to change the pose ?
This is actually a forum for Photoshop Elements which is a slightly different program than Photoshop 7 but I’m still interested in your question. We may still be able to help you.
Hi Todd,
About the way I can think of to change a pose is to flip the photo horizontally. You do that by Image>Rotate> then either Flip Horizontal or Flip Selection Horizontal … dependant on the make up of the image.
If that is not what you are looking for then do let us know.

If you want to move something within the photo you can often do it by careful nudging with the liquify filter, but it’s very fiddly, time-consuming work and the result may depend a lot on how good an artist you are if you are trying to do something more elaborate than just repositioning an arm, say.
