Tackk: Content Creation Startup Tackk Expands Its Visual Library With 500px Integration

Tackk is announcing that it has partnered with photo-sharing startup 500px, making a wide variety of photos available to Tackk users. Tackks, for those of you who don't know, are basically pieces of content combining text, images, video, and other media. The company originally described them as "e-fliers" but the company now says it "allows anyone, to create anything, and share it anywhere."
