This probably lives squarely in "who cares" territory, but:
1. Click on reputation number on top of page to go to reputation page.
2. Note which image is displayed as the Image of the Day (IslandWorld).
3. Go to a normal forum listing, e.g. by clicking on For Beginners.
4. Compare the images in step 2 and step 3.
The image listed on the reputation page is always displaying the same image, never-changing. Ever-watching?
Would expect the image on the rep page to be the same (and shifting daily) as the one on the normal forum listing.
