Can´t find good theme. HELP! PLEASE.

Hello there, I am looking for some “special theme” or plugin for my next project.(worpdress) .

Just be very brief, it will be about pictures mostly, so I need good gallery theme or something like that. It could be Pinterest or Instagram style or something like this: The problem is, that I don´t need “portfolio style”, that after click on some photo it will redirect me to another page, where is project desciption. I would like some “pop up” on the same page, where will be details about current photo and sharing options like in those pictures? Any ideas how to solve this? Thanks
