Well if you ever let other people use it, you're probably going to need some kind of server-side script to resize the images before they get sent to the browser, otherwise you'll have people making galleries of 10+ megapixel images, which might put quite a strain on the server.
PHP or Sinatra would probably be suitable for something like this, basically anything that you can upload images to and which will create thumbnails and preview-size images automatically.
That said, browsers these days are quite good at resizing images so that's less of a concern (unless people visit using IE<9). I might have a go at making a simple lightbox thing, as I will need one for my caerphoto.com site eventually, and it's an interesting challenge. |
