My site is currently ranked very highly in google images for a popular search term, but I am not sure why. Basically I have a gallery of pictures with no description. Anyways the search terms, are for example, "celebrity nude", "cebrity naked", however the terms "naked" and "nude" appear nowhere in my site for those pictures. It's strange that im ranked so highly, when those words don't appear on my site. Can anyone shed some light on this?
