Well, it is a 15-year-old static image. It won't be changed. Judging from a pastebin linked from a neighboring comment however, most domains are quite specific enough that pixels can be left as is (you can't really use "clinicalimaging.net" for something other than, well, clinical imaging). In the other words you are really buying a domain and its historical legacy including pixels.
