If one is sufficiently slapdash, fixing something on this site each day is more than doable. A couple of days ago I did some work to tidy up the display of Reviews. Deeply fancy logic (not) to check the name of an image file seemed to do what I wanted. I had forgotten, however, that while the name I gave the image file was constant, it respected the file format of the original image file. My logic was testing for only one file format.
