How do I move the picture behind or ahead other picture

Sometimes, I have to delete the first picture which is the default picture and make a new default picture. However, each time I do this, I have to unlink other pictures to make the new picture to the default picture.

Is there a way to move pictures behind or ahead other pictures?

Thanks
