gallery - add to lightbox

[design]

Hello! I'm working for a photographer. He asked me "add to lightbox" function (see for example istockphoto) - a place to add own favorites pictures.
Is it possible using DIV Gallery Content part and FE login? Have you never did it?
Thanks!

Hey

this would need some custom programming... cannot imagine any function of phpwcms will do this with any trick...
