TGIF.
Thank you for your help during the week.
I tred rebuilding everything and ended up on the phone to Apple in Portugal who in the end suggested i create a new iphoto library from the masters. Many photos and annoyingly the Project book i was working on have vanished. Depsite many back ups to Time Capsule. I can see project files but i cannot make them open in iphoto for some reason.
As soon as I created a new iphoto library from the masters the images all disappeared yet again!
I closed iphoto and reopened it and the images are now there, except for the many ommissions.
I cant understand where my photos are...When i click on picutres all i see is a little icon saying photolibrary (several times over). When I was a windows user i could actulaly see the names of the photos and it was much easier to just select them and deal with them. I cannot fathom Finder or how it is supposed to make life simple.
Anyway, I have decided now to abandon iphoto altogether unless anyone here can give me a reason why this has all happened so that I can ensure it doesnt happen again. If it is just a matter of iphoto being unstable, then I will use Picasa. I do not want to spend days yet again filling in faces and creating projects and albums to then have it all disappear without any trace of a backup.
I opened Picasa last night and have 3000 photos that have not been opened in years. All intact. So that is a positive.
