I wanted a fuss-free way to share a directory of images. Kinda like what I would've done on Tumblr, once upon a time, but even easier.
At the moment it shows a randomised group of three whenever the page is loaded.

I was going to add and render a little bit of metadata stored in separate files, but haven't bothered, and don't know if I still will.
The first-draft was more like a blog, was sorted by file name and had multiple pages.
This one's a very simple bit of PHP:
<?php $images_all = glob("images/*.*"); $images_picked = array_rand(array_flip($images_all), 3); foreach ($images_picked as $image) { echo '<img src="' . $image . '">'; } ?>
