The Yahoo spending spree continues this week with the company's acquisition of mobile photo editing app maker GhostBird Software. This is the company behind apps such as KitCam and PhotoForge2, both of which were withdrawn from the Apple App Store as of yesterday.

According to a statement at the company Web site, the technology behind these apps will be integrated into Yahoo’s image storage and sharing service Flickr. “There has been so much exciting progress at Yahoo! as they re-imagine their most-loved products for mobile, including the awesome new Flickr apps for iOS and Android,” the company wrote.

Financial details were not disclosed. Yahoo did not issue an official press release, but merely tweeted news of the acquisition. Yahoo has been rolling out new versions of its core mobile properties in recent months. Flickr is among its more popular and best received apps, currently the 24th-most popular download in the free photo section of the Apple App Store.

This acquisition comes on the heels of last month's big buy of cross-platform blogging site Tumblr. In fact, the two acquisitions may not be unrelated. Both properties emphasize user generated and blogged images. Flickr enjoyed a major redesign at the same time Yahoo acquired Tumblr. “Photos make the world go around,” Yahoo CEO Marissa Mayer told VentureBeat last month.
