Trashing iMovie's preference file will often fix problems, but may not help with your situation (but worth trying).
Go to your User (Home) folder Library/Preferences (not the Library folder at the top level in Macintosh HD). Similar to Mountain Lion, on Lion the User Library folder will be hidden (unlike pre-Lion OS X versions). To access it, click on Go in the Finder menu bar, then press and hold down the Option key - the Library folder will appear in the drop down list, enabling access to it.
In the Preferences folder, locate a file named "com.apple.iMovieApp.plist". With iMovie closed, drag this file to the Desktop. When next opened, iMovie will create a fresh preference file with the default settings (you can change these settings in the menu item "IMovie>Preferences" if desired). If iMovie is now running smoothly, it's OK to drag the old preference file to the Trash. Trashing the file will not harm your existing Events or Projects.

Thank you. You helped me remember how to find the Library folder (it was hidden)- forgot the Go+option trick. I did as you suggested and then opened iMovie. On opening, iMovie began optimizing events (assume that happens since the file was missing). I saw that a new file was created and I had to re-adjust iMovie preferences, as you said. I then tried to add pictures to the project and it still did not work.
I did check and the new project I created with added pictures worked fine. So- there is still a corruption somewhere. I did not try rebooting my iMac (call this a "Hail Mary" pass)- just in case that helps. If it does, I will update my post. But- I still have the problem.
Anyone have any other ideas I could try? Thanks.
