[Plugin: Rotating Posts] rp_content to display image

Great work – thanks for this plugin. I am trying to get the custom field rp_content to display an image as you suggested in the installation guide. I am using:

Name: rp_content
Value: absolute path to the image

But what is displayed in the rotator is the absolute path and not the image itself. I am a bit new to this, but any thoughts on how to make this work. It could be something very simple I am missing.

Thanks
