Obviously there are some different opinions here.
My relationship to profiles and photos is closer to Bunnie's:

Either way, whether you decide to put one up or whether you decided not to… it does still tell something of you. And it does weed you out for others who don’t share that same value, so there’s that.
My motto is, set up your profile however feels right for you… that is how you will find someone who is attracted to who you are… quirks and all

Personally, I have an aversion to taking/sharing photos of myself and the comments that those pictures invite, so of course I did not post a picture of myself on here. This worked fine for me as I wanted to meet someone who was more attracted to my words and personality than just my physical body. I happened to luck out and find exactly that - bonus points that my Master and I are also incredibly attracted to eachother's physical bodies once they were shared in photos.
However, I can imagine that for some, the physical attraction does come foremost - and how tragic would it be to feel sparks flying in your dm's, only to eventually have things not work out because, in the end, you just weren't physically attracted to each other?
I would bet that putting up pictures of yourself will probably bring you more attention - from both the right weirdos and the wrong ones, becaue let's face it, we're all weirdos here - but you can decide how necessary that is. My advice would be that it is possible to find potential partners without the profile picture, so if you don't post one, consider sharing photos fairly early in conversation with potential partners, this might lessen the chance of disappointment or feeling like time was "wasted" if you are not mutually attracted to eachother.
