hmm, now that's a neato toque-twister for the morning.

I know Dreamweaver can do global updates to many index files at once, so it should be able to resize all the images - to me both actions are more or less the same (change & save).
I do not use the proggy so I can not detail the steps, but you should be able to list the source, or Src as 0001.jpg.

Sorry I could not help out more.
