How to Delete a News Feed Photo on Facebook
Your Facebook news feed keeps you up-to-date about what all of your friends have been doing. When a friend updates her status, comments on another friend's wall, posts a link or shares a picture, it appears in your news feed. From time to time, you may come across a picture in your news feed that you do not wish to view. When this happens, hide the picture so you no longer need to see it in your news feed.
Log into your Facebook account and find the picture you wish to hide in your news feed, then hover your cursor over it. This makes an "X" appear to the right of the picture.
Click the "X." This brings up a list of several options, starting with "Hide this post."
Click "Hide this post." This permanently hides the picture in question from your News Feed. If you do not wish to see anything by the person who posted this picture, click "Hide all by (name)" instead.
