Store img tags in database and retrieve it

You can read this post on CKEditor:

Image Path

I use this filemanager with CKEditor and the links are setup like above link.

Responsive Filemanager

The filemanager has an image path setting in its php config file.

how this will help? If I insert hundreds of img tags into database while developing on localhost, how the img source path that stored in database, will be proper path on live server while outputting images?
