Mark Zuckerberg posted a picture on on Friday while visiting Walmart’s corporate headquarters in Bentonville, Ark., furthering speculation that the social network is looking to grow its partnership with the retailer.

The news comes as Walmart and Facebook is to make an announcement as early as Saturday regarding its partnership.

It’s unclear at this time what that could mean for both companies. Walmart is already a major advertiser on the site, and the retailer has carried Facebook Credits — gift cards for virtual money that can be sent via Facebook games such as Farmville — since 2010.
