This article walks you through how to replace an artwork image.
To replace an artwork image, you have to first add a new one. You must have at least one image per artwork at a time.
You can add a new artwork image by following the steps in this article Adding Multiple Images of an Artwork.
Once you have added another image, you'll be able to remove the previous image. Ensure that the image you would like to keep is listed as the ‘Current Primary Image’. You can then remove the other image(s) by clicking the red ‘X’ button.
As best practice, it is recommended to have at least two images on each artwork.
Note: Changes made within CMS can take time to process. This change could take 24 hours to appear on Artsy.net.
