I was in need of an Ajax-style animated gif that could be used to indicate that something is going on in the background or loading. I have seen them on hundreds of sites, but I don’t feel comfortable just copying someone else’s image to use for myself.
After a bit of searching, I found this site: AjaxLoad.Info. This is a nice, simple site that generates 37 different “loading” animated gifs, allowing you to customize the style, foreground and background colors, and transparency. Definitely a good site to know about.
