Some images are displayed upside down.  The image is stored in the repository with the correct orientation and the thumbnail is correct.  Either Djatoka or the Workbench Image viewer is inverting the image.

Examples - The photos are all in the correct orientation on my computer’s photo viewer. Here is the path to one of the folders with the photos: https://workbench.sidora.si.edu/sidora/workbench/#si:2795506?path=si:2794556,si:2833,si:2795499,si:2795504
