Photos & Comments

Ok so i was testing the photo and comments i noticed the following.....If user(A) makes a post on the timeline and ads multiple photos and a video or not a video, user(B) visits timeline and clicks on the photo, they will be prompted to the actual photo they clicked on. Now to the right of the photo there is a section in which user(B) can leave a comment. User(B) leaves a comment, user(B) goes back to the same post on the timeline and clicks the arrow on the right of that post to view the second picture of that post, the next picture will rotate from right to left(Obviously) so now user(B) clicks on the second picture and is prompted to view that photo, now here is the problem, the comments that were posted for the first picture, are posted for all the photos on that specific post. Please view sample's. Hopefully my description here makes sense.
