To share artwork to Facebook or Instagram, you will need artcloud's mobile app, which you can download for either iOS or Android.
Step 1: Manage Mode
Once signed into the artcloud app, make sure you are in Manage Mode of the account and not the Market Mode by clicking Account -> Manage Mode. Manage Mode allows you to control your own inventory while Market Mode allows you to explore the artcloud marketplace.
Step 2: Select Inventory
Now that you're in Manage Mode — head to the Inventory tab and select the piece for sharing. At the bottom of the inventory profile, you'll see the channel options for sharing.
Step 3: Share
Along with Pinterest, Instagram and Facebook sharing options you're also able to send an SMS text and Email message containing a link to the piece of inventory on the marketplace.
