It is not possible to assign one single image to multiple collections.
The only way to add artwork to multiple collections is to upload the same image again for each collection.
- You have a Landscape painted with oil and you have set up Collections for both Landscapes and Oil Paintings.
Upload the image of the painting twice, assign one image to Landscape Collection and the 2nd image to the Oil Collection.
IMPORTANT: if the exact same piece is assigned to separate collections and is sold from one of the collections, the other image, assigned to the 2nd collection, will still show as Available for Purchase! Be sure to manually mark that item as sold!
- You have a piece that is available as the original painting and as a reproduction print.
You have set up Collections for both Originals and for Prints.
Upload the image of the painting twice, assign one image to Originals Collection and the 2nd image to the Prints Collection.
NOTE: It is helpful to alter the title, like so:
"Pear with Apple ~ Original"
"Pear with Apple ~ Print"
