He couldn't explain what it was. So he took a picture of it to show someone who could help him.

That is really not all that disturbing. It's not like he is using it for child pornography purposes. If he cannot explain it's best he show a photo if he needs to.

For exactly this purpose haha. His child's pediatrician could have also asked for a photo so they could see how bad it was, etc.

He clearly has a picture to show, I'm assuming, the pharmacist (OP?), to see what cream would be best recommended. It's a good tactic for something small that may not need a doctor's visit.

That's not how it works. In that case, parents who change their children's diapers were viewing child pornography and doctors who give physicals are child molesters.

It's not being indecent. The father didn't know what it was and I'm sure the kid was freaking out as well. And I don't think this should be a FML because it's the OPs job to look at this type of medical stuff and help them understand what it is.

We don't know their job. OP could work at a general store for all we know. Pharmacies aren't the only places that sell medication.

It's likely the son is an infant and has diaper rash. My friend's a pharmacist and people are always showing her pictures of their (or their kids') gross rashes. It's gross and TMI, but not creepy.

I'm agreeing here. It "could" look bad if someone wanted to "get" him and showed the pic to the police, but it would probably blow over when they saw most pics were of the kid dressed as some minecraft character, his spouse's cooking fails, cat's antics, etc.

Who said OP had a child?
