Ghostrider:
I'm no expert by any means, in fact, I have a lot of problems getting girls to meetup through internet dating, but that's NOT because of my profile picture. I get way more messages than I can read. My problem is girls never have the nerves to actually meet up (that's the reason I'm here).
I only have 1 profile picture. If girls ask me to prove it by sending another picture, I generally tell them no or ignore them. They won't think you're fake if you're not making excuses for it. Or they're still willing to take the risk that you may be the real deal and continue the conversation anyway. If I really like the girl then I might send another one where I don't look like I'm expecting somebody to judge how I look, and that always locks them into chase mode again.
Your profile picture, old and new, have bad body language and convey that you are nervous. A good quality picture doesn't change this. You hunch, you have a nervous smile, your hands are nervously closed and to the front of your body. Everything about you look stiff, shielded and scared. ("please like me and don't reject me" vs. "oh hey camera, how are you?")
Me telling you this is most likely NOT going to help you making you feel more comfortable and confident and make a photo that DOES create a nice image of a confident, sexually attractive male that I'm pretty sure you actually are.
But you need to know these points before you can move beyond them. And now you can
Instead of trying to go out and get 30 or so photos in a particular spot, or more.... get used to taking a camera with you and taking lots of photos anyway, not necessarilly about you. Do new things, do fun things, go out of town with friends, go rafting, climb a mountain, do some scuba diving, whatever is adventurous and will get your adrenaline going! AND!! make some photos while doing that or/and have friends take photos. You can always cleanup and enhance photos afterwards anyway.
The difference here is that it will take your mind off of trying to create that perfect photo, with all the right posture and body language, and it will be a lot easier to actually relax, be comfortable and thus get that great looking photo.
And practise doing silly poses, just for fun! Try to do a few exaggerated alpha male/superman poses, put your chest ridiculously forward, strike some bruce lee poses, whatever, just keep it fun. And somewhere during that will be that great photo for you. You might actually find new levels of confidence and also meet a new lover while at it. At the very least it will give you stories to tell at social interactions.
I believe the quality of the photo is not as important as the body language you convey THROUGH that photo.
Seriously, I took my photo when I just woke up, was horny as hell and had slept a night in a horribly dirty hostel in Bandarawella in Sri Lanka. I made 3 photos, all came out blurry, but 2 of them conveyed raw sexuality.
Women see that photo, they pick up the sexual part of the message in the photo, and the rest they just make up to fit their ideal man.
"I can see you are a wild man/I can see you are into fast cars/I can see you're exotic/I can see you're a really sweet snuggly person/I can see you're a straightforward, down to business guy/I can see you're very energetic/You're a guy who likes sports/I can see you must be a guy who likes animals/etc. etc."
I don't give a shit about cars, music festivals, football or whatnot, they just want their hot guy to be like that so they lie to themselves with me as their object.
Just as men lie to themselves about women they want, women do the exact same about men. If their lie of me matches the real me, I might reply to them, or if they are really hot I might play along for a bit.
If you want more success with your profile, give them a profile they can tell a story/lie to themselves about.
Most women don't even bother to read my profile text. Don't mention your work, it's usually boring. Mention something silly that does not make you look like a slob. Use movie quotes or something if you don't have inspiration... Look at guy's profiles that are popular and copy what they're doing.
Best of luck!
