Occasionally, an image will be rendered left/right reversed--but only in interlaced mode. In anaglyph mode or any other mode, it renders correctly. For instance, see http://phereo.com/image/52deddc6cb8577eb7900007e (which renders correctly in windowed mode, but reversed in fullscreen mode), or http://phereo.com/image/52dedc41cb85776079000074 (which renders reversed in both windowed mode and fullscreen mode).
These are the only images in this album that render incorrectly. Other images in this album render correctly in all modes.
Of course I can click the "Swap" button to reverse the left/right images, but that is just a workaround for an obvious bug. I shouldn't have to reverse the images for just these two particular photos while stepping through the album.
I don't know what's unique about these photos. Perhaps they have an odd number of rows? It's difficult to tell the image size from the web interface or from Phereoshop (I don't see an interface to show the image size anywhere, in fact).
