Eleonor: Thanks for sharing that interesting link, quite useful but as most of the commenters point out, it does use JavaScript (well a DOM event at least) and won’t work without JavaScript enabled. But the advantage of that one is that it uses only one line of JS and doesn’t need a whole JS framework library. But the framework libraries add the sexy extra animation effects, etc. A couple of those guys that commented did come up with some CSS only versions though, which are quite impressive although lack in extra functionality (like navigating the gallery, displaying captions, etc)…

Don’t be afraid of DOM/JavaScript! Just make sure it works acceptably with JS switched off! Switch off JS and try my example. Works completely accessibly…
