Obviously I'm way behind the times. I thought images were being flagged because of keyword descriptors. But you're saying there is software that is, in effect, "looking" at the image data itself? To use a silly example...

If, circle surrounded by circle, surrounded by circle, analyze colors.

If color of t inner circle is black and color of outer circle is white, color of middle circle is irrelevant. "Collection" is an eye. Skip to end.

If color of both inner and middle circle is pink and color of outer circle is beige, then "collection" is a bare breast. Flag for "violation".

End routine.

I didn't think we had reached that level of pattern recognition.

Sincerely,

Bill
