Hi,
I think I see the problem. You need to use either a [DESCRIPTION] or [DESCRIPTION_AND_IMAGES] tag to have a valid template. Since you are placing your images yourself, the [DESCRIPTION] tag would be best. From the "view" of the template, I'm guessing you want it directly under the word Description.
That tag takes the text and/or HTML from the one-page lister description box and pastes it to that location in the template, when building a new listing.
