In full screen, iMovie does not show entire photo or title page

Would you post a screen shot showing your timeline and the preview screen? Are the photos cut off when you display the project in normal view, or is it just in full screen? What operating system and iMovie version are you using?

Check your crop settings (the icon that looks like intersecting angles in the tool bar at the top right of your screen) and set it to the "Fit" setting.

If the above is not the issue, try opening iMovie while holding down the Option and Command keys and selecting to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects. Now see if iMovie properly displays your photos and titles.

You can also try creating a new project and seeing whether the photos display properly there.

All else failing, you can redownload iMovie. Drag your old iMovie app from the Applications folder to the trash, but do not empty the trash. Then sign in to the app store and open your purchases folder by clicking on your name at the bottom of the app store sidebar. You will see iMovie displayed among your other purchases. Re-download or update iMovie from there. See if that cures your issue.
