Missing Media Collections?

Richard L Dickson

Running a Topic Guide on "Feasts and Festivals" gives a MEDIA RESOURCES section and a MEDIA COLLECTIONS section.  Clicking on the images in the MEDIA RESOURCES section pulls up a resource containing the image.  Clicking on the images in the MEDIA COLLECTIONS section either doesn't do anything or opens the Media Tool with a blank space, no image.

Can anyone explain the difference between these two media sections?

Also, in the MEDIA COLLECTIONS section, are these perhaps coming from resources that I do not own?  If so, it would be really helpful if a link to the Logos Store was given.

Thanks.
