Problem embedding images in rss feed via builder?

I am having no luck embedding images/s in an rss feed I am creating
using a builder template.

I am sure my image path is correct... I have tried image paths as
strings as well and I have placed the xml.image block within the
xml.item block as well as an option. Ultimately I need the image tags
to be in the item block as each news item will have its own image. But
the sample code below has the image block as a direct child of the
channel tag for simplicity's sake.

Any thoughts on what I am doing wrong?

Thanks! Elliott

Anybody have any ideas on this one?

Thanks
