Hi Karl Mikesell,

The imageUrl property is not supported by RadEditor for ASP.NET AJAX, which has new toolbar architecture based on image sprites. Using a new client-side model, semantic rendering, and many other innovations such as the use of css image sprites, the new RadEditor delivers minimal and well-formed output. Its new rendering and architecture allows it to be a couple of times faster than the classic ASP.NET Editor.

The only supported way to set an image to a custom tool is to provide image file for it and output the following CSS class in the page with the editor:

<style type="text/css">
.reTool .MyCustomAction
{
background-image: url(MyImage.gif);
}
</style>

as shown in this article: Adding Your Own Buttons.

Best wishes,
