Online photo service Shutterfly has purchased create-your-own-web-site company in a deal the two companies say was for under $15 million.

Redwood City, Calif.-based Shutterfly will use Palo Alto, Calif.-based Nexo as an easy way for its users to share their photos together on the site, such as for this sample family’s site.

Nexo launched almost a year ago, with angel backing (our coverage).

Meanwhile, Shutterfly, a publicly traded company, has been having a rough time — its stock traded sharply down last week, amid concerns about a larger recession, as well as about a sharp price cut by competitor Snapfish.
