I needed a way to scan a lot of photos at once. I was going to write a GIMP plugin to extract out multiple images from a single scanned image of 3 or 4 photos, and then rotate them automatically. But as always, someone had already beat me to it :)

See this forum on GimpTalk for the original script.

(The only problem I had is that the Deskew plugin for GIMP is located on a website whose server seems to be permanently offline. I did manage to find an alternative location, so I've posted a self-hosted link to the plugin below)

Steps to scan in multiple images:

• Download DivideScannedImages.scm to
  ~/.gimp-2.6/scripts
• Download deskew to /usr/lib/gimp/2.0/plug-ins
• Start GIMP
• Click Filters -> Batch Tools -> Batch Divide Scanned Images

The rest is easy to figure out. Just make sure your 'size threshold' is large enough. Also, it may help to cover the photos with a couple of sheets of A4 paper, to give an even white background. Then place a few photos (3 or 4) on the scanner, with adequate spaces between them, scan them, and let the plugin do the rest!

Thanks to RobA for the awesome script!
