In this case, I have to defend those without digital cameras, scanners, and web cams. Not everyone can afford or has the know-how to be able to get a pic online. Doesn't mean they are a bad person or hiding something, as long as they are upfront about it.
I too prefer pics, but I don't automatically delete them if no pic. I will review the profile and respond one way or other.
One thing I have seen done is to post a pic and then make a forum post. Delete your pic, and for some reason the forum still has it when you post. Don't know if it still works, but it is one way to get your photo out there but not all the way out there.
And for all those ladies who have said it doesn't matter what a guys looks like, it's what's inside that's important, how many of you delete the guys if they don't have a pic? Not exactly living your own words, are ya?
