San Francisco-based Wallop, a startup that came out of Microsoft's research lab, is testing out a social networking site that will charge users to put decorations and other graphics on their Web pages.

The decorations will cost from 99 cents to $4, the company said (fourth item). The site is invitation-only for now.

Wallop also said today it has received a $10 million round of Series B funding led by Norwest Venture Partners.
