To turn off all the images in all the posts:
1) Click on "User CP" at the top right of your screen.
2) Click on "Edit Options".
3) Under the "Thread View Options", select "NO" for both "Show user's avatar in their posts" and "Show image attachments and [img] code in Posts"
By doing this, you have shut off all the linked and attached images on the board. And saved the admins a little bit of work.
