this is the URL of the link, not of the image. if you right click the image in the editor, you can enter image settings, where the URL is displayed (if it is not a css background image).

OK. Thanks.  Now i know what the image is for that module on that home page because you told me.

How do i, as a programmer or a DNN administrator for the site that wants to put his own content in that module, find the name of that file and replace it with my own.

Thanks,
Tony
