I notice what I think is a bug in the Permanent sharing system.
From a URL in the non-public part of my /app, e.g. https://www.permanent.org/app/public/00eu-024o/375107
I click a particular image to share it.
I even see a helpful tooltip!
If I click View on the Web or copy the apparent permalink, https://www.permanent.org/p/archive/00eu-0000/record/00eu-0286, it refreshes to https://www.permanent.org/ and shows an index of my content instead of the desired image.
