replace image without deleting the current image

Hi,

I would like to ask if there is a way to replace the images in the listings without deleting the image permanently.

Here’s a screenshot: https://imgur.com/BDTJWYi

I’m using a single placeholder image for the whole listing. I wanted to replace the others picture but the only way I see is to delete the current Image permanently. I just wanted to replace the current Image without deleting any other image. Thanks in advance.
