I found the following page today when I was searching for an image to display whilst waiting for a web page to load.
http://www.ajaxload.info/ (opens in new window)
I wanted something like the nice spinning circle used on Windows Vista.
The page takes a few simple values (foreground/background colour etc.) and then creates a nice spinning circle graphic which you can then download.
It will also allow you to choose from 35 different graphic styles (e.g. circles, bars etc.) for your image.
This generates a GIF image similar to the following:

i seen a website one where you clicked on a image to view it larger, and it brought up a gray window iwth that in it to load the image, then it showed the image all faded, any idea what code that is? i would love to put it on my website
thanks if you know
Joe – I think you’ve been looking at a page that uses something like the Lightbox Javascript code (see here: http://www.lokeshdhakar.com/projects/lightbox2/ or http://www.huddletogether.com/projects/lightbox/).
These are very easy to set up and very effective in displaying a large image without the user leaving your current page.
