Due to the simplicity of snapping a photo with one's smartphone and placing it on social media channels, many people are stuck with zero attribution to their work, so Tagg.Ly is aiming to fix this.
The device is an app that can be downloaded from the Apple store, which can easily add a watermark to your photos. The app was developed by a journalist for VICE who noticed his work being shared multiple times, which was fine until no credit was given. To combat this, he invented Tagg.Ly as a simplistic way to mark one's work, and demonstrate that even smartphone images still rightfully belong to the person that took them. Hopefully this will help crack down on new sites stealing other people's work.
