Justin Tadlock 10 months ago WordPress doesn’t have a concept of an “anonymous” role or user. Members can only control capabilities (permissions) of roles in WordPress. And, because the concept of an anonymous role doesn’t exist in WordPress, this is outside the scope of Members. There’s a reason WP doesn’t allow this sort of thing. Allowing anonymous visitors to your site to upload images is a huge security risk. I wouldn’t risk it. I don’t know of any plugins offhand, but you’ll need to specifically search for a plugin that allows visitors to upload images.
