I think it sends a signal to a lady that you are a pain in the ass.  Not a good way to start off the session even if her pics were taken yesterday.  

You're much better off staying away from BP, where fake pics may be a common problem, and sticking to ladies with good reviews.

When I'm looking, I read her profile, I check her ads, I check her web site, if available, I read her reviews, especially the most recent ones.   Going in, I am pretty well assured the picts are real & recent.  
If there is not enough data, I might ask her for another picture...  say if only one or 2 are displayed (already a red flag for me).  
Based on this, I'll go ahead or not.  I'll not insult her by questioning her photos.   IF I show up & they're fake, it has to be a instant decision to turn around.  I'd not give her any notice.  In this business, you both know why you're there.  She knows the rules on fake or out of date photos just as well as we do.  

I've come close, discovered one on my bucket list using old photos...  no longer on my list.  But I've not gotten as far as the door since I found TER.  A couple before TER.  

If you use the tools, this can be reduced to a small risk.

In fact, it is a good question to ask.
If the photos are currently dated on her website then it may not be a good question to ask.

I don't ask if they are accurate. I ask how old they are. If they are more then 6 months old, then I count the extra pounds and add age to her face.  

Don't worry about "getting off on the wrong foot" If she is insulted by the questions then she either has a bad attitude or 20 extra pounds. Move onto the next one. You don't want to be the next dude to write a review that she was fatter or older and loose your hard earned cash at the same time.

several guys who have seen her, say she is who they expected to meet, seems to work. There can be times when someone gets the old switcheroo, and that's happened with one lady I met, after I saw her, though not with me. If she had done it to me, I would have just walked. I just don't like to accuse the lady up front of false advertisement, which is what you are doing. But, that's your call, and you'll win some and you'll lose some. Good luck!

It is, however, pointless.
It's not like you're going to ask someone about their pictures and get a response like "you know what? you got me. You're right. My website pics are 10 months and 25 pounds ago. I'm glad you asked. I've been dying to get that off my chest".

What you're talking about is the difference between a perfect world and the one we live in. In truth you'll find that only about 15% look like their pictures. Between pics that have been touched up, tans faded, workouts put on hold, and good old fashioned not giving a shit, there aren't many accurate representations out there.

Now you ask about bringing it up at the time of the meet and walking away? Well that's a whole other issue right there. While guys will jump out from all four corners to tell you how they won't stand for it, the bottom line is that 99% of the pussies do. There's the old "well I'm here, she's here, and I'm horny" train of thought.
And (can you see the connection here?) THAT'S why the women get away with it!!

Yes...males should act like men...value their time and money...and have a backbone. Buuuuuut....they don't. As I've said before...you can't expect women to not take advantage of "men" or think they are stupid....when these very same "men" do stupid shit and make taking advantage of them so incredibly EASY.

It's true that proper, dedicated research will help guide you...but it won't keep you from ever having a negative surprise. It's how that surprise is handled that defines a person.

Good luck out there....it's a tricky place.

until after the fact to ask a question like that. Just because I'm curious. One lady admitted, "yeah, that's not me." But she was close enough (and hot enough) that I didn't give a shit. Don't think I would ask before the fact, unless she looked like Linda Evangelista in her photos and Linda Tripp in real life!

but I don't think I'd follow up with "okay, well I hope you're not lying to me because if you are a liar, I'm going to walk away" which is basically what you're suggesting.

Read her reviews and see what folks say about the accuracy of her pictures.  

Asking this question is always going to get you an affirmative response from the lady since she is either (a) telling the truth or (b) trying to hide something from you.

You don't have to warn her that you will leave if she isn't the girl in the pictures. Just leave.

I agree if you go with a well-reviewed lady and actually read her reviews you have your answer on if the pictures are of her or not.Like another reply said if some lady is using fake pics or pics that misrepresent she is not going to tell you this in an email or a phone call.If the lady is not the one in the pictures when you arrive do a U-turn and hightail it out of there.Like I said in another post regarding fake pics why reward bad behavior by staying if the pics are not real.It would seem if you stick with well-reviewed providers this would not be an issue.

I would not say to the lady if these are not accurate pictures her appearance is different that you are not going to see her.You are already started out on a bad foot and you have not even laid eyes on her yet.For the ladies that you do contact that do have accurate pictures they may decide to pass due to the way you come off if you decided to say what you posted.Some figure too much trouble in the beginning and the appointment hasn't even gotten started yet.It seems the guys that run into the fake pics are TOFTT and got the short end of the stick if you do your research you have less of a chance of seeing a lady with pics that do not represent her.
Just my .02

Your question isn't out of line, and is even understandable. I've been asked that question a few times. When I'm asked, I say yes my pics are accurate, but I won't take the appointment. While I understand why the question is asked, you come off sounding like an inexperienced newb, who is destined to get caught up in a sting. When that day happens, the last thing in the world that I want is to have been a lady you have seen. So I want to stay away from you at all costs.

A better strategy is to pass on the reviews that state she didn't look like her pics, and book ladies who's reviews say they do look like their pics.

When calling unreviewed providers,  I have been tempted to let them know upfront that it will be a waste of both our times if, upon our meeting, she is not as represented in her pictures.  That is, to strongly imply that I will walk if I feel misled.  I haven't done this yet, though I have walked, and as noted, it is a real waste of both our times.  I wonder what the thoughts are on this.

Choose providers with lotsopics. Anyone can look great in one or two carefully cropped shots. Those who really have it show it!

Good Point!

I believe the reason that these women are doing that is because they know that the average guy doesn't have the balls to tell her to go home or simply not answer the door. I think that hobbyists should make that a regular way to handle the situation that way people who have real pics (like me) do not loose good potential customers. We both put ourselves at risk in different ways and need to be able to feel less nervous by not getting screwed by each other all the time.

We have choices.  This is an expensive hobby and I want to optimize my experience.  With few exceptions, if the ad does not show face photo, height, weight, and to a lesser degree, price then I keep shopping.  Also if the photo looks TGTBT, then I pass.  Finally if the chick is obviously not the chick in the photo I walk.
