I have done more troubleshooting. This error is related to one specific photo out of 30. Each time the thumbnail creation step reached that one photo, it bombed out in the creation of thumbnails.
When I placed photos from that gallery on a Page, the Page threw the same error as above. I had to delete that photo from the gallery completely to get the Page to work.
I need to use that photo, can you tell me what to do?
