I was all about the pics, and when I was on the site, many men didn't even hide their faces. I think blurry your face is a good suggestion, and gives a potential an idea if they have attraction. I also appreciated a good body pic, ideally a front facing one (head can be cut off).
When I was on there, there were so many men, that it was easy to make a first pass based on physical attraction and then read the profile. If there weren't any deal breakers, it really depended on the chat. I would usually try to meet for coffee/first meet relatively soon. That was the ultimate litmus test.
Just providing a perspective of someone who needed that initial physical attraction to a man's pics, in order to want to learn more.
