JPG lets users submit photography content based on a chosen theme by the JPG editors. Themes range from titles like Fashion to Beauty Redefined to Embrace the Blur. Users can upload one image per theme, which are then voted by other users based on quality and theme-matching. JPG editors get to make final theme selections.
The JPG site has plenty of interaction around upcoming themes, submitted and published photos and stories. Users are encouraged to leave comments, vote and submit work. You can even add contacts and start making friends. If your photo makes it into an issue than you get a free one-year subscription plus $100.
JPG’s print issues come out six times a year, but issue content is available online at all times. Users can even download PDF versions of issues for free.
