iPhotos thumbnails

[omeletpants]

My young son got hold of my Mac and changed all kinds of settings randomly.

iPhotos used to come up as a screen with all the thumbnails. Now it opens into a screen with just one photo. The show thumbnail in the toolbar is greyed out. Any ideas?

Check the scaling bar in the lower right corner of iPhoto. If the dot is all the way over to the right, drag it to the left two notches, or more as need be to bring more images into view.
