I am now seeing early reports of a Google Image Search update via WebmasterWorld. The reports claim that Google has been adding new images to the image index and those images are now showing up in the search results.
That last Google Image Search update was in October and we see them every few months or so.
There is no word on if there was an update to the image filter. But we may see more reports coming in on that news soon. So, if you have been waiting for your new images to show up in Google, you may now be in luck.
