this question comes up a lot on my online thread so you can find extra tips there but yes it does matter!
You want good pictures. Things of you out and active doing whatever you like doing. Playing poker, basketball, dancing, etc. Whatever it is you do get pictures of you doing that. Pictures of you with women also help display pre-selection. Pics of you with guy friends as well so you don't get the player vibe and showing you have healthy relationships with men as well.
Always use current photos, no older than 6 months. The more the better! Women love going through pictures of guys online.
Have fun!
