I think professional photos should be done one a year if you have glamor shots taken. I know they are expensive and will not be done more than that. A lot can happen to a person in one year...weight gain, hair style change, or hair color change. I've even seen girls go from a blond, stripper look to a more mature, elegant look with a different hair style and color in one year. I've even seen women go to a pixie haircut (which I hate) and still have photos posted with her having long hair. Immediately Im confused. Is she blond or brunette? Is her hair long or short now? So obviously in these scenarios, pictures become outdated once a woman changes her look, or her style. If a woman gains weight, we all do, but still has photos up with her being 25 pounds lighter, that is outdated. I remember a local provider I saw last year who had pictures up for a long time and I based my decision to see her on those photos. When I got to the room, that wasn't her anymore. She has gone on to update those photos, and it is now an accurate representation of her, but I was not happy when I arrived to find out the person I was seeing was not represented by the photos that were available.
As much as I like professional photos, and how much I believe it makes a woman look more professional on her website, you have to look at the pace of social media these days to answer your question. Twitter accounds, snap chat, facebook etc is the way the world is now. I think its smart for any business, to post frequently on blogs and so on. Posting selfies are cheap and can often be great quality with a good phone and proper lighting. You can even attach selfie sticks to some inexpensive digital cameras with an LCD screen that flips around so you can see yourself, because the screen side camera lense for selfies on many phones is a much lower quality than the main camera lense. There are also apps you can buy for just a few dollars that allow you to touch up your selfie photo. I use one called Facetune.
A lot of guys like myself want to see what you look like in the moment. When I'm looking at literally hundreds of girls, I often chose the girls who have selfies that are recent. In many cases, I think the girls look better in the selfies than the glamor shots because I love the outfit she had on while she was at home, or how cute she looked in her car, the way her hair was put up and the pose she struck at that moment. I looked at your profile just now and I love the picture of you from behind wearing the hat. Its the only photo I can see how beautiful of an ass you have. Its actually the only photo I see out of those posted that shows how feminine you are. The other two posted doesn't look like you're the same person. You are much more chiseled in the other two. The only way to combat that is to post new pictures often. To refresh the old ones and throw up new ones frequently so they don't become 'stale'. Please dont take offense to what I am saying. This is simply constructive criticism. Out of the three photos you have on P411, I see one with you in the hat and Im like WOW. The other two I dont. So if a lot of guys are thinking the same thing I am, why would you want those two up for a really long time? To answer your question and not blow sunshine up your ass, which Im sure you dont want, update your P411 photos every quarter, or every 6 months and post 1 new photo on a Twitter account weekly. I think this makes all the difference in all business these days. New content frequently is a good thing
