spiral loading gifs, loading.gif
I came across www.ajaxload.info while searching for a spiral loading gif online. It lets you create a custom color gif to use while your page is working. It has all sorts of loading bars, similar to the Firefox and Internet Explorer page loading images. Unfortunately, I was looking for a larger one; perhaps there’ll be one in the future.
On a side note, check out Google’s horrible job at contextually serving its AdSense ad. It’s for: Loading Dock Levelers / Full line of loading dock leveler with load capacities of 160,000 lbs. Yeah… that’s a product that all web developers want.
