Images are inserted into your description using the location and layout that you specify on the lister page when you use the [DESCRIPTION_AND_IMAGES] tag. Whereas individual [IMAGE#] tags will show up in the normal flow of the HTML. So instead of the individual, numbered image tags, you may want to try [DESCRIPTION_AND_IMAGES] or any of these:
[IMGS_VERTICAL]
[IMGS_PAIRED]
[IMGS_HORIZONTAL]
[IMGS_SLIDESHOW]
[IMGS_THUMBNAILS]
