Any site member can view any profiles public pics (unless that specific profile has been blocked) regardless of whether they have chosen to be a site supporter or gender.
Your gender, or level of site supporter pass makes no difference whatsoever to whether you can see people's photos or not. They are either public, friends only, or private.
"Can non supporters see photos. ..I have been told that females and couples can but not males. .is this the case..seems a bit off to me if true..
"
Check your privacy settings, unless you block single males, they will see them.
