Media Link

Trying to figure out how this plugin works. All I need to do is remove the domain name that is part of the image link shown here:

and just show the image links that are in the upload folder

/wp-content/uploads/2014/12/post_img_42.jpg
/wp-content/uploads/2014/12/post_img_32.jpg
/wp-content/uploads/2014/12/post_img_42.jpg
/wp-content/uploads/2014/12/post_img_12.jpg

Reason for this is incase I need to switch the domain name this way nothing is lost when I switch over.

Hope that makes sense?
