Visual file/photos management system

Hello! I’m looking for nice and simple photo library but not for photographer. My client sells many articles but not via Internet. Sometimes he needs to show his product to his clients, for now we used dropbox for sharing the content but we need new funcionalities, most important: creating client (time limited) user accounts with optional folder or file assignation.

Please help if someone has web based, ready to roll system like that - it may be WP.

Best regards,

Mark
