Actually details are critical
What version of iPhoto? What is SWOD? How did you send "several photos to trash" and are y0ou talking about the iPhoto trash? Did you empty the iPhoto trash?
I thought they had fixed it so we could do many pix before it quit working properly.
What exactly does this mean?
iPhoto 11 ver 9.4.3. Spinning Wheel of Death. I was scanning through my iPhoto library in the iPhoto window, I clicked on a pic I wanted to throw away, (oh, I was in the "Photos" section of the Library in the iPhoto window) then clicked a pic, clicked up in the menu- Photos- Move to Trash. (That is iPhoto trash.) No, I didn't empty it. Years ago, when I first got my eMac, iPhoto had a problem, if I tried to edit more than a few photos in a half hour, or tried to make new albums and transfer pix from one to another, iPhoto had problems. Up would pop the SWOD. Very frustrating. I thought they had managed to correct it after all these years, Oh, well.
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
Thanks Old Toad, I needed a laugh. I thought of that the first time I heard of the Spinning Wheel of Death. Wonder why the other guy who is a level 8 never heard of it? Maybe he didn't need to read the Mac for Dummies, I'm still glad I bought that book. I'll try the library rebuild if it happens again, right now, I'm way too tired to think my way through it. Appreciate all of you.
