Embedding an image with PHP

I'm creating a simple website with php scripts as just kind of a little project and I want to be able to show pictures on my site. I've visited some sites before that show their images like so (hopefully you know what I'm talking about by looking at that picture). Is that program/script/开发者_如何学编程whatever free, and if it is, is it newbie friendly? And are there any other good-looking ways to embed a picture?

Its not really PHP, but more javascript. You want to take a look at jquery lightbox

You're talking about scripts like Lightbox.

It's free and easy to integrate if you follow the instructions. Search for lightbox alternatives if you want a different look or whatever.
