But Google images are hot linked, so I think you might want to turn off your hot link filter. Something must be set up wrong. As much as I dislike hot linkers I've never enabled "prevent hot linkers".
Of course another thing to experiment with is how many of your images show up in safe search.
I found one page of one of my sites didn't have images in safe search but they were there otherwise. This particular page linked to an electronics site, to a page that talked about male and female sex! Sex of electronic connectors that is. I removed this outbound link to a legitimate site and in about 3 or 4 months "poof" my images from this page were back in the "Safe search" results.
