Theme/plugin photo gallery and video presentations

Theme/plugin photo gallery and video presentations is the theme I want to get some answers.
I want to make a small web page with photo galleries and video presentations. It is a kind of a gift for Christmas for my father :slight_smile: He likes mountain climbing and taking photos and creating powerpoint (powerpoint 2003-very old) presentations and then he sends his friend this large files. I want to make now a small site. Is there some great themes and plugins to do that? And even to transform powerpoint to video.
