An image sprite is a collection of images put into a single image.
A web page with many images can take a long time to load and generates multiple server requests.
Using image sprites will reduce the number of server requests and save bandwidth.
Generating a sprite from scratch in, say, photoshop can take a lot of time. That is why I wrote this
very easy to use, no-nonsense sprite generator. It supports full alpha transparency, just select your
files or enter a website URL and your sprite will be generated for you at no cost.
You will even get the complete CSS (Cascading Style Sheet) that you need to use your sprite with
all the calculated image locations.
