Log in to UnitPrints, and from the menu at the top of the screen click ‘Albums’. Then, click ‘Create New Album’, create a name for the album and accept the copyright statement.
When you make a new album, UnitPrints will ask you to begin uploading photos. You may choose to upload photos from your computer by clicking in the upload box OR by dragging the images you'd like to upload into the center of the upload box.
After photos have been uploaded to the album you can add additional photos by clicking “+ Upload Photos” button along the right sidebar.
