On ebay I can see the gallery picture but can't click on any other available picture. Firefox won't access them. I have to switch over to Int. Exp. to see the other pics How can I fix this problem?

Question

Also, if I do a Google search and a list of things comes up, in all the picture fields there won't be any pictures. There are other sites that this occurs on also, and on some places that ask me to type in a series of misshapen letters, I can't see those letters.

Answer 1

As Larry says, restoring the back up is the fastest and best solution. Otherwise:
Option 1
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 Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords 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. .
