Yahoo Chief Executive Officer Marissa Mayer has reportedly set her sight on Imgur. The San Francisco-based photo sharing startup could be Yahoo's next big acquisition. This was according to a Business Insider report, which cited an unnamed source, wrote VentureBeat.

While Yahoo has been on an acquisition spree of smaller startups last year, the firm might have more difficulty with Imgur, the report said. The site is very popular, with more than 100 million unique monthly visitors. It is also profitable, although the startup's exact revenue is hard to pinpoint. Aside from that, Imgur does not have any outside investors. Because of these combined factors, Imgur's founders could settle for a very favorable acquisition sum, the report explained.

Imgur has lots of traction and influence across major social networking sites including Reddit. Should the acquisition deal push through, Imgur could help Yahoo turn Flickr into a more social and appealing site like Instagram, the report said.

Both Yahoo and Imgur have yet to comment on the acquisition news, VentureBeat reported.
