Articles Structured Data Problem

Hi
a couple more things here
Can you tell me a way say in Fields to add the image from the item. for all items
mark up along the lines.
itemprop='image' itemscope itemtype=' schema.org/ImageObject ' itemref='??'
or itemprop='image' ??
at a guess.
it will only find image from gallery in mark up which on 3000 items only have a few gallery views
so just the first picture is fine same as the OGPfinds.
also the mark up id is not unique as it ends item/flexicontent
OGP this is correct as shown.

thanks for any help.
(i am learning alot)
