Re-link lots of images? Indesign CS3

Hi - I posted this in the indesign forum and it was suggested to look here. I've had a quick look for a solution but thought I'd post aswell.

"Because I've resaved a load of jpegs to psds the links are now broken.

Is it possible to relink them all without doing each one manually?

The update link option is greyed out. All the psds are in the same folder. "

Thanks again
