How can I restore photos from my ipad? My computer -- with its attendant photo library -- was stolen, and now the only copy I have of many pictures is on my ipad. How can I transfer those photos to my new mac?

I tried the instructions from here but these only found photos in the "Saved Photos" album, not all photos.
You need a 3rd party app like

(there are others, search Macupdate)

Note that the images will have been optimised for the iOS device so they may not ne as large as the ones on your Mac.
