Trouble getting thumbnail to open fully in the main window for editing.

Question

I updated to 6.0.6 iphoto and I can't find a way to have my thumbnails taking up the whole main window...not the full screen. Previously when I double clicked on a thumbnail the pic opened in main window, taking up all the space in that window. Now it is just a small pic in the main window and I can't see enough detail to edit the pic.

Answer 1

The files in the Data file are the thumbnails used by iPhoto. The ! you're getting is because iPhoto has lost the link between the library and the original files that will be in the Originals folder.
I don't think it will work but you can try to rebuild the library as follows: launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library. Select the first three options.
If that doesn't work you'll have to start a new library and import the files in the Originals folder from the old library. Here's how:
Creating a new library while preserving the rolls from the original.
Move the existing library folder to the desktop.
Launch iPhoto and, when asked, select the option to create a new library.
Drag the Originals folder from the desktop into the open iPhoto window.
This will create a new library with the same rolls as the original library. However dates on the rolls may be different but can be edited as you would the roll title.
Once this is completed you can delete the Originals folder from the desktop and the iPhoto Llibrary folder. If desired, you can keep the older library folder to try other fixes on it.
In the future I recommend you make a backup copy of the Library6.iPhoto file after each import and after doing a lot of editing and organizing in the library. Then if you experience a similar crash all you need to do is replace the damaged database file with the backup copy and you'll be back to the same place in the library as when you make the backup. See the tip at the end of my signature.

TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
