When I click on the Source Tab on this profile, I get a pop-up window that says, "We weren't able to retrieve the data you requested. Please try again later."
I thought perhaps that it was because the primary manager may have limited public access to the profile, but after working with Curator Erica Howton to try to resolve the problem, it seems to be a bug. She says she's having similar difficulties accessing jpegs that are uploaded as sources.
