Several months ago I disallowed my image folder/directory in robots.txt.
Intitially this worked well and with-n a short period of time the number of my images showing up on Bing Image Search using a site:www.example.com search dropped about 4,000 images and showed only 4 random images that were in folders that hadn't been disallowed.
Yesterday the number was back up to 3,200, all in the disallowed image folder.
Anyone have an idea why that would happen?
