iphoto replaced by clipart

[sarahwarah]

on a shared login my son dragged all my photos from my iphoto to his, via the shared folder, which removed my permissions from mine. I have managed to get most of them back through backups and reversing the procedure, but some recent ones have been lost.
Some seem to have been replaced by clipart images. The revert to original option is grey. Is there anything I can do to get them back?

Find the moved iPhoto Library and highlight the whole Library and do a Get Info (command button+i) and the Info window will come up. At the bottom of that window is the Permissions settings and make sure you add the new username to be able to read+write to that Library.
