Problem
Product images have disappeared after you clicked the remove button during editing.
Possible cause
When editing an existing product, removing an image deletes it from the server immediately — as soon as you click the remove button. You do not need to save the product first. This action cannot be undone.
Solution
Upload the image again using the image uploader on the edit screen.
Save the changes after uploading.
If the problem persists, contact support and include details about:
The product name.
When the images were removed.
