How to remove image URL automatically

I share images from different sites and these sites give a URL to the image!! Users who are coming to my site are clicking on the image link and never return to my site!!:mad:

I normally share galleries and it is a huge task to remove each and every URL from it!!:(

Are there any tools or codes which on adding or applying would remove the links or make the links effective!!:confused:

Note: Since I am using galleries i cannot add one piece of code to one line of the gallery images!:eek:

Thank you in advance!!!:thumbsup::)

There are plenty of gallery scripts available. So we can't guess the one at your end and try to find out a solution.
