How to Attach a Photo in a Comment on Facebook
One of the ways Facebook lets you communicate with a friend is by posting a comment on his personal Facebook wall. This comment does not need to include only text. Instead, you can can include a link, a video or a photo if you so desire. You have two choices when it comes to including a photo: you can use one that you already have on your computer, or you can take a new one with your webcam.
Sign into Facebook. Navigate to the wall on which you wish to post a photo with your comment.
Click the Photo option in the "Share" section, just above where you would type a text comment.
Click either "Upload a Photo" or "Take a Photo," depending on your preferences. Either take a picture with your webcam or navigate to the picture on your computer that you want to post.
Type your comment into the field below the wall, and then click the blue "Share" button to post the photo and comment on your friend's wall.
