I've done a search for photos with "HTC One" as the camera model (to pull photos from my cellphone) and created a dynamic album.
The album shows up properly with image thumbnails.
When I click a thumbnail to view the image however, I get a 404 error.
Zenphoto Error: the requested object was not found.
Album: HTC One
Image: IMAG0097.jpg
This happens with the default theme.
