We've added a "Revert to original" button to the product media editor so merchants can revert image edits after saving. This is beneficial because merchants no longer need to reupload the original product image to revert edits. If merchants want to revert a cropping, drawing, resizing, or edit with Shopify Magic, then they can revert to its original state using the "Revert to original" button in the product media editor.
