If I lock a folder as private but not the individual image, can you see the image but nothing else in the folder? Yes, If you give someone the direct link of an image in PB, that's the only image they can see.

I should make you a private folder. Not necessary. The folder I have been dropping textures in for you is not locked but the only thing in the folder is textures for you and you are free to share them, if you wish.

The folder I put my icons in for challenges is locked, because for some challenges we aren't supposed to let any one know which is your.
