I am working on large website (to many images, posts, large database), and I need to change almost every url of image in wp-content/uploads/ to target a one specific image. I have tried with WP RegEx Replace plugin, using this instructions but it's not working. When I try to change specific url of one image it work, but if I want to select all images using wp-content/uploads/(.*)/(.*).jpg it's not working.
Do you have idea how to do this?
