The picture of the girl holding her ID isn't required by 2257, it is however a good cover your ass. We shoot that once for each new girl we shoot. We also do a video of them saying that they are not currently under the influence of drugs or alcohol, and that they were in no way forcefully coerced to take part in the shoot. When we sell content to others we do include the pic of the girl holding the ID. But it isn't something that needs to be filed with your 2257 documents for your records if you were inspected.
So to answer your question. Personally I would just make sure you have 1 clear shot of the girl holding the ID for your own records, and if your customers request it I dont see any harm in passing it along.
We shoot in an area that is covered by the recent
6th court decision so currently its unconstitutional in our state, but we still make sure we maintain our records as required, and above and beyond those requirements simply to cover our own asses if we ever have any civil suit, or any questioning at all we have everything to make certain there is 0 question.
