I was recently asked in conversation if it would be possible to have a list of items, and when a user mouse'd over the headers in the list, an image effect happened, IE a thumbnail image was displayed. I figured this would be an ideal use for JQuery, so this article is how to write an incredibly simple JQuery image change.

There is a full demo of this here: JQuery mouse over demo

This article deals with a work around for a problem I had been experiencing with the imageCFC ( http://www.opensourcecf.com/imagecfc/ ) open source project. When resizing an image the file permissions were being lost on the edited file. This meant that the server operating system could not read or serve up the file to the browser.

I've been using imageCFC as I have a variety of coldfusion server versions (7 and 8), and I like the fact that in the resize method you can specify the maximum size for the width and height, and it will resize down to that size, and keep the aspect ratio of width-to-height.
