Atomic / Pinnacle Drinks Relationship?

I've noticed Endeavour Drinks and Pinnacle Drinks have used stock photos of Atomic Pale Ale on their website.

I'm aware GDA have had a contract with Pinnacle to brew their brands (e.g. Sale & Anchor) for some time, but I've never interprated this as being involved in GDAs own brands.

Is this a mistake, or is Pinnacle involved with Atomic? I do note that Atomic returns no search results on Pinnacle's 'our brands' page.
