While looking for interesting on-the-fly image resizing techniques, we came accross a ridiculously easy-to-use PHP script for resizing images the smart way. Created by the Joe Lencioni, the guy behind Shifting Pixel, this little piece of gold consists of a single PHP script, that you'll put anywhere on your web server along with a companion folder named "imagecache". And then you let the magic begin.

All you have to do from now — and believe us, it's really as easy as that — is to src to the script in every <img> tag you want to get a thumbnail for, with the proper querystring. Your tag will then look like something similar to:

<img src="image.php/output_image_name.ext?
     width=nnn&height=nnn&
     image=path_to__image.ext" />

Oh boy, it works like a charm!

But wait, there's more: thanks to this script, you can also get square thumbnails. These add a definitive classy touch to your pages, and just require a simple extra "&cropratio=1:1" argument in the call. Isn't the world a beautiful place? And since the usage of the script is fully transparent for the developer, it can be called from any host language — as long as your webserver runs PHP and GD and your language outputs valid (X)HTML!
