Multiple photos in iphoto
I downloaded the new iphoto app in the last couple of days and I'm having a lot of fun with it (particularly like the 'Journals' section) but I've come across a weird thing. When I go to the 'photos' tab, lots of my images have been duplicated several times; not all, some x3, some x5. It's not because they appear in multiple albums, or that I've edited them several times, and when I look in the albums the images belong to they just appear once. Anyone have any idea why this is happening? And is there a way to delete the excess images from the 'photos' tab (couldn't find any solution in the iphoto help bit)? Any help would be appreciated.
