Digital Railroad has raised $5.2 million first round funding from Morgenthaler Ventures and Venrock Associates.

The NYC-based company, which makes web-based applications targeting professional photographers, said it plans to use the money to expand its photo distribution, management, and archiving platform.

The company already offers photographers digital workspaces with tools to edit, display, and sell images. Earlier this year, the company introduced RSS feeds for photo buyers, which help them get customized streams of images that match their interests.
