Switch JCarousel from manual to automated or automated/manual and superimpose a transparent play button on custom graphic

I have 2 small projects: (1) Superimpose a transparent .png play button image over a custom graphic. I want the play button to be vertically and horizontally centered. I also want the play button to be the only clickable part of the image and not the custom graphic. When clicked on, another window will open to a youtube page and play a video. I have a sample play button image which is under the images folder.

I still want the arrows to highlight like they are when going through the images. It would be great if the carousel could be BOTH AUTOMATED and MANUAL if while the carousel is running, the viewer decides to go back an image or two. Then, the automation would start back up after a second or two. (See the folder named kuck). [login to view URL]
