Believe it or not, something similar happened to me. Based on the replies in this thread, I’m beginning to think it’s not all that rare.
I vote for a big dose of C.
To me it is very obvious what to do. (Of course I’m not the one in the predicament)
I would send her a short email that just said “I received your photos and I was confused by the message. I would appreciate you not emailing me any further. I wish you the best in your future endeavors.”
Unless of course you want to play cat and mouse with her
Does Hustler still do Hustler Honeys, where women (more likely their “boyfriend” or “friend”) would send in amatuer porn shots?
Submit it as “friend” and laugh on your way to cash the check.
Doing that would absolutely incite that game of cat and mouse that you’d like to avoid.
I saw nothing in the original note that was contemptuous or meanspirited. If you don’t think he should communicate with this person any further, then blocking the email address would make a lot more sense, since doing so gets the job done and is nonconfrontational.
I don’t see any malice. If she was trying to say something along the lines of “this is what you’re missing,” then the joke’s on her, not him, as he now as naked pictures of her. I think that unless his ex is a real dummy, spite’s not on the menu.
She’s effing with you, plain and simple. The easiest way around it is to sit back and let her take her best shots. The less interested you seem, the more exotic she’ll get, and you can reap the rewards, which will probably culminate in her throwing herself at you.
Don’t laugh. It’s happened to people I know.
In order to gague how likely this is to happebn for future advice, I need to see her…umm…ummm…eyes. Yeah, the …ummmm…look…in her…ummm…eyes. Please forward the pictures via my e-mail link. Trust me, it’s the only way.
Congratulations!
this is really beautiful!
::wipes tear from eye::
Huh? Did you forward the pictures on to verbenabeast and not the rest of us? That’s not fair. Post a link for all of us.
Ignore her. No response needed.
Or…possibly…She mean to send you a picture named, say, DCP05409.jpg, a picture of her dog next to a waterfall; but sent you DCP05408.jpg, a picture of her in the altogether, by mistake. In which case the whole situation is comic, rather than just plain weird.
Your best bet is to just pretend it never happened.
And share. 
Lucky you.
All my ex-girlfriends ever send me are restraining orders.
This reminds me of a friend of mine - he had this crazy gf…they finally broke up. Months later she sent him some photos of her and her new bf on the beachin Mexico. They were all these bikini shots and all posed for telling him how she had gotten over him - blah, blah…he never answered her email.
Well six months after that he ended up getting married to someone else and GUESS WHAT? The psycho email sender showed up!! All in tears apparently not as over him as she had implied. Fortunately several friends saw her first and headed her off before she could ruin the wedding.
Maybe she needs closure?
Folks that are asking to look, I doubt that you really want to.
I should be clear that they’re fairly demure-- mostly “see my panties” sort of stuff. It might also to be helpful for y’all to know that she’s twenty years older than I am. She keeps herself in trim, but still, disabuse yourselves of the notion that we’re talking about ideal wank material, here. It’s also heavily and inexpertly photoshopped – we’re talking “Go crazy with the ‘artistic’ filters, but leave the red-eye alone” – it boggles the mind.
The one that seems most noteworthy to me has her perched on a (towel-draped - ewwww) barstool, wearing naught but a black shirt, printed canvas sneakers, and those weird ruffled anklesocks. She appears to be digging in her cooter, but that might just be misinterpreted modesty.
Some of the filenames she’s given the pics are a little odd, too. There’s a pic of her on her kitchen counter that she’s called “alicemagic”, which seems to be a reference to a little framed print that I gave her for Xmas 2001, which is on the counter behind her. There are upskirts pics which she’s labeled “forU” and “forUtoo.” I don’t know if that’s for the public at large, or what.
Anyway, I don’t want to alienate her altogether, I just don’t want to be in any kind of intimate situation with her. I place a high value on being able to walk away and say “Um, good luck with all that,” when things get completely incomprehensible. Which is pretty often, with her.
That is solid gold, man.
Who are you to tell me what I want? Let me make that decision for myself. If nothing else, I can rephotoshop (which is now officially a word- screw you grammar police!) them into something of which you’d be proud.

Yes, yes. Do share.
A few jobs ago I worked as a tech support trainer. Every 2 weeks I’d get in a new batch of 20 or so techs to teach our software and troubleshooting procedures to. After I had left that job one of those former students sent me a few collage pictures of her wearing lingerie in various poses. My wife was not pleased.
So is the towel-draped barstool.
Ugh
Ha! What would be really choice would be to spoof it so’s it looked like it found its way to this guy.
(Huh… I see I got my #1 Google ranking back-- He had me licked for a long time, what with his ministering to the injured at Ground Zero, and all that. Attention whore.) 
Grim_Beaker, I hope your wife saw those because you showed them to her, and not because she happened to be looking over your shoulder when you got them. Yipes.
I think Happy Scrappy Hero Pup may have fainted. (Maybe that “She’s twenty years older than me,” wasn’t as illuminating as it could be, without the contextual “…and my school days weren’t exactly yesterday, either.”)
