It allows one to quickly generate a loading gif, which can then be used … for whatever.
One may choose the colour, background colour or choose transparent background, and the style of the gif. There are over 15 styles to choose from, ranging from rotating circles to simulated loading bars.
So next time you need an animated GIF, and can’t/can’t be bothered making one yourself, head over to Ajaxload.
Which one did I use? You’ll just have to wait and see…
