Well done. Kept me engaged to the last picture. A couple of observations though: The left-right keys still advance to the previous / next picture in the background, when the comments are in the foreground. Suggest that a left or right hides the comments as well as moving forward or back. I second the comment made elsewhere on pre-loading the next picture to save your users waiting for the load-time. How do I navigate the comments with the keyboard? I use the cursor keys to scroll down, and it doesn't work, as up / down is mapped to show / hide comments.
