WPPA images stopped showing in photo of day and photo album

WP Photo Album Plus had been working perfectly. Now images are not being displayed in either the sidebar Photo of the Day nor in the photo albums, only image name. Images are on the server and can be viewed via file folder.

They did seem to stop being visible after I installed the set of Simple Facebook Connect plug-ins. I deactivated all the SFC plugins, but images still are not visible.
