We would like to turn off YouTube's recommended videos in the player. I figured this can be done by passing "rel=0" to the YouTube video URL in the embed / iframe.
I tested this by adding rel=0 on the iframe URL and it worked. I tried adding rel=0 to the YouTube URL I used in the Slideshow Video, but that did not work.
I also figured prettyPhoto supports this attribute if present.
But am not sure what changes do I need to do to achieve this results. What files do I need to change? Where?
