I recently started using Photoshop Elements, and I am puzzled. When I drag a thumbnail in iPhoto to the Photoshop Elements icon in my Dock, it opens the photo in Photoshop Elements. I can then edit and alter the picture and save it.
But in iPhoto, the thumbnail remains as it was; it does NOT reflect the changes I made to the file. If I doubleclick the photo to see it in edit mode (still in iPhoto), THEN the changes are there (so they were indeed saved with the file), but the thumbnail in the main iPhoto window is somehow not updated. Is this normal? What can I do to have my thumbnails reflect how my Photoshop Elements-altered pictures really look?
Thanks for your help/clarification!

This might shed some light into how iPhoto works....if you browse around in the Pictures folder in your user Library, you will see that iPhoto stores the Thumbs, the original JPEGs, and when applicable, the edited JPEGs, all in separate sub-folders. (You can browse, but dont screw around in these folders or you will break some links needed for iPhoto to work properly).
So now the question is what happens if you first trash the original photo in iPhoto, and then re-import the Photoshoped file into iPhoto. Or alternatively, rename the Photoshoped file befoe you re-import it?

I have since discovered that, if you set iPhoto preferences to open a picture in Photoshop when you double-click it (instead of opening edit view), then the altered photo DOES get an updated thumbnail! If you then Option-double-click a photo, it opens in a new iPhoto edit window.
What I'd like is for the regular double-click to open a file in edit view (not a separate window) and for Option-double-click to open it in Photoshop, but I do not believe this is an option...

Harmon:
Yes, you can have it both ways. After setting it for PSE go back and set it for Main window. Now you can Control-Click on a thumbnail and select Edit in external editor in the drop down Contextual menu. That will give you PSE.
The is one caveat to editing with PSE that you may already know of. If your edit involves layers or other types of changes that require an extension change to ".psd" you must save it to the Desktop and then import as a new file - that is if you want to keep the layers. Otherwise select "Flatten" image from the Layers menu and then you can save as a jpg normally.

Thanks Old Toad, I didn't know that! I'm just getting to know photo editing and PSE, and all advice is welcome...
