John, I'm sorry if this is unrelated to Kieth's post, but the browser is not showing his other images. Is there a good reason for this or is there a glitch in the system?
I have noticed a few other species pages with (seemingly) locked images that never change, sometimes with less than the standard number of 8 images, even after new posts are made available on the "images" pages.
Should they be reported in the forums or should I just sit on my hands? (Who are you gonna call? Ghostbusters!)

Guide pages can be locked at a certain set of images, and if not only the images with the "representative" setting are displayed. The setting is only visible to editors. It is on when a photo is first submitted. I turned off representative for the genitalia photo I featured on the web page, for example. I also generally turn it off for ventral shots, because those are not usually helpful to people browsing.
