Lumani, it was pointed out to me that I responded to your question as if you were asking about your players instead of other people (non-members) seeing your images. The correct answer to that is no one but those that have joined your campaign can see your art assets that you uploaded and then it is only if you put them in the map area, handouts, or a journal entry. If you have your campaign setup for public viewing and have art assets in a handout or as an avatar in a journal (character sheet) with them assigned viewable to all players, they can be seen that way. Maps are not seen that way still. Sorry for any confusion my post might have caused.
