-## Image threads
+## Add a comment to an image
 
-Sometimes a thread is revolved around an image. With image threads,
-you can easily target a specific coordinate of an image and start a thread
-around it. Image threads are available in merge requests and commit detail views.
+In merge requests and commit detail views, you can add a comment to an image.
+This comment can also be a thread.
 
-To start an image thread, hover your mouse over the image. Your mouse pointer
-should convert into an icon, indicating that the image is available for commenting.
-Simply click anywhere on the image to create a new thread.
+1. Hover your mouse over the image.
+1. Select the location where you want to comment.
 
-![Start image thread](img/start_image_discussion.gif)
-
-After you select the image, a comment form is displayed that would be the start
-of your thread. After you save your comment, a new badge is displayed on
-top of your image. This badge represents your thread.
-
-NOTE:
-This thread badge is typically associated with a number that is only used as a visual
-reference for each thread. In the merge request thread tab,
-this badge is indicated with a comment icon, because each thread renders a new
-image section.
-
-Image threads also work on diffs that replace an existing image. In this diff view
-mode, you can toggle the different view modes and still see the thread point badges.

-on diffs (not on the merge request discussion tab) appear collapsed on page

-## Lock discussions
-
-For large projects with many contributors, it may be useful to stop threads
-in issues or merge requests in these scenarios:
-
-- The project maintainer has already resolved the thread and it is not helpful
-  for continued feedback.
-- The project maintainer has already directed new conversation
-  to newer issues or merge requests.
-- The people participating in the thread are trolling, abusive, or otherwise
-  being unproductive.
