OP - can I be just a tad direct here? Yes? Excellent
Am gutted (both for you, & just per se, and obviously for anyone impactd by him) that your old Uni mate turned out out to be a vile l'il perv.
That said though, you are - genuinely - not just having an over-reaction here, but bluntly a WHOLLY skewed view of this (apols, but can't help but be direct here.)
CONTEXT: your DC was WITH YOU; was in a SUPERVISED PLACE; with a photographer HIRED BY THE NURSERY.
Nice bloke of that generation did what countless others have done - and hopefully still will do as long as not utterly terrified they'll have their cards marked as a potential paedo
- and very simply wanted to give your beautiful and well-behaved child a gift.
But you were (& I believe you) freaked out, stunned, & believed yourself to be off-guard. You didn't NEED to be 'on-guard in first place. Manifestly you were there, your child was at NO risk, and this was just a bloke being nice. Agree with those who think you and DH may^ be taking this a little too far & honestly beg you NOT to 'raise it' with Nursery Owner. Worst case scenario is some poor sod just doing his job AND being lovely will be ejected from that Nursery; and best case scenario is you really will look like a bit of an eejit (Irish term - you know what's coming next don't you?

Yep, it is VERY common for this to happen in Ireland, and - IME - here too. My PFB was stunningly beautiful, very literally people would stop me in the street to comment on just HOW perfect he was (and he really was, unlike 2 other DS's who frankly looked like Winston Churchill when born to point where we both modelled front cover of Mother & Baby Mag etc) and he was literally showered with money by all and sundry
Tis a tradition and one I think is sad older people feel they can't do anymore.
Can I suggest you look at THIS THREAD for some context? And then listen to your gut, and not your - however validly given news stories etc. - head?
Is also HUGELY important to talk to your child re strangers etc, but you HAVE to be clear with them about the difference between 'proper' strangers vs. people they simply don't know but are perfectly safe with as you are (were....) there. THAT is a lesson you seriously do not want to balls up for DC as is a world of difference between the two, but IS vital your DC understand which one IS dangerous, and which one isn't...
