Ok girls, lets be real for a moment

No not really. If I'm friends with the guy and I like his picture then it means nothing, or sometimes I won't even be friends with the guy really but it's just a cool or funny picture of himself so I 'like' it.

No, sorry. We might like the colors , the place where the pic was taken, the other guy in the pic with you :P , your dog.. don't get carried away.. girls notice everything . BUT - if she likes every pic of you on Facebook then yeah, probably ..

I would have to disagree.
You're definitely reading into it too much...
Noticing someone cute and liking their profile pic doesn't mean you want to have sex with them..

No, you are over thinking to the extreme and you honestly sound a bit creepy

._. if I like your profile picture its because its a nice picture. Even if I don't know you, know of you, are acquainted, got drunk and gave you a lap dance once, its all the same.

I don't flirt by liking your fb picture I flirt by inboxing you for your fone number and hittn you up or commenting your picture callin you sexy I mean really. Even then it probably has no real depth to it just fooln around. Not like seriously going to want to bone because you took a nice picture xD

Not flirting...

If I "like" a picture, I like the picture.

That's it.

Don't read too much in to things.

It really depends on how often she likes your pictures. If I like a guy, I would like his pictures often. Sometimes I would like a picture just because I think it's cool or something similar to that as a once-off thing.. If it is often, then she does like you.* :)

No its completely different. When I like guys pictures sometimes I'll think he's good looking and sometimes I'm trying to be nice or like the way the picture is taken. It doesn't mean, hey he is hot lets have sex. Its just a picture haha.

No I could just like the picture itself, I've liked pictures of guys I wasn't interested in because I thought the picture was nice or funny.

Well, sometimes you like a guy but don't "like" the image because you don't want all your/his friends to see that you did and then start gossiping.

Nope. Not all the time, sometimes, I just like how the picture was taken.. Or the guy could be a friend I'm comfortable with..

if she likes one of your pic, than it's nothing. if she liked half of all your pics than it is a different story.
am I right, girls?

No, I don't think so. They may just like the picture, it doesn't have to mean they are interested in you. I don't like (as in click on like button) profile pictures on Facebook often, but when I do it is a girl but I'm not always interested in her. I just like the picture, how it was taken, or the situation in which the picture was taken. So while it's possible a girl is flirting with you when she likes your picture, it's not necessarily the case.
