Good job @raviteja4117 on this issue. You setup the branches correctly, made the correct code change, and prepared a well-formed and descriptive pull request. The code checks out fine in the browser (although note that the image is only displayed in mobile views).

Confirming the PR was written correctly and descriptively like Roslyn said, and the closing "/" has been removed for consistency as mentioned. Good job @raviteja4117 !
