Top Videos section above matching tweets during search
For now, Twitter shows Top images to the left of the matching tweets when you do a search. As this rolls out, the image/video will now appear above the tweets.
Also, if you click on an image to view it, you will now see the tweet on the bottom of the image. Similar to how Facebook has it via your mobile app. See the image below which was shared by Search Engine Land.
