One day, after photojournalist John D. McHugh grew tired of people using his pictures without attribution, he created his own watermark app. Called Marksta, it guarantees that no matter where your photos appear (say, someone else’s Instagram profile), they have stamps displaying your copyright privileges. If you too are worried about others stealing your work, check out five more of your best app options that’ll protect your creative work. Huzzah!
