(4) Producer does not include persons whose activities relating to the visual depiction of actual sexually explicit conduct are limited to the following:
(ii) Mere distribution;
(v) A provider of an electronic communication service or remote computing service who does not, and reasonably cannot, manage the sexually explicit content of the computer site or service.
Doesn't it sound like it could make Google Image not a producer?
If it is, why wouldn't a thumb TGP be included there too? The only thing they are doing is distributing.
