Giant exclaimation point in iPhoto

the link to the original is broken - have you run any clean up software like CleanMyMac or MacKeeper or others (Hint - do not they are really bad news) - or have you been deleting photos from the all Files list (again never do this)?

What has changed since it worked?

If you haven't run any "cleaning" apps like Larry mentioned give this a try:

1 - launch iPhoto with the Command+Option keys held down to open the First Aid window. Be sure to follow the circled recommendation in the screenshot.

2 - apply Option #4, Rebuild Database.

Did you have the PSE Organizer set as the external editor in iPhoto's advanced preference pane and was using that to edit photos? Or did you go into the library via the finder and edit the files?

If you want to use PSE as the external editor from within iPhoto see the following:

Using Photoshop or Photoshop Elements as Your Editor of Choice in iPhoto.

1 - select Photoshop or Photoshop Elememts as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.

2 - double click on the thumbnail in iPhoto to open it in Photoshop. When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done.

3 - however, if you get the navigation window

that indicates that PS wants to save it as a PS formatted file. You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.

This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..

With Photoshop Elements the Saving File preferences should be configured as shown:

I also suggest the Maximize PSD File Compatabilty be set to Always. In PSE’s General preference pane set the Color Picker to Apple as shown:

Screenshots are from PSE 10

Note 1: to switch between iPhoto and PS or PSE as the editor of choice Control (right)-click on the thumbnail and select either Edit in iPhoto or Edit in External Editor from the contextual menu. If you use iPhoto to edit more than PSE re-select iPhoto in the iPhoto General preference pane. Then iPhoto will be the default editor and you can use the contextual menu to select PSE for your editor when desired.

Note 2: editing a RAW file with either PSE or PS creates a new file which must be saved outside of iPhoto, i.e. the Desktop, and imported as a new photo into the iPhoto Library.

Note 3: do not select the PSE Organizer as the app to open from within iPhoto. Instead select the Adobe Photoshop Elements Editor as shown in this screenshot:
