In December 2007, we reported that Google's image search filter was a bit too sensitive and it filtered out many non-adult images as if they were adult images.
We have new early reports from WebmasterWorld that some Webmasters are noticing more and more of their images being taken out of that filter and showing up in normal "moderate filter on" Google Image searches.
A very senior member, Zeus, who once had only 80 images show up with moderate filter on, now has up to 5,000 images showing up. It has been a few days so far and Zeus had not come back to say his images were temporarily released, meaning it may show that his images are out of the filter for the foreseeable future.
Are your images still being marked as adult? I did post some tips on How Do You Get Your Images Out Of Google's SafeSearch Filter to give you some options.
