Image Pan Help

Hello,

I am designing a website that has a rather large image as it’s background. I would like it to pan rather slowly vertically, fade out and into the next image which again pans vertically. I have a series of 10 images I’d like to showcase like this.

Basically I am really inspired by http://www.group94.com/#/website/work/portfolios/ and would like to replicate a similar effect. Although I am sure knowing them it’s very technical and done with video and xml etc.

I am very limited in my knowledge of AS unfortunately and thought the Interactive Image Pan tutorial could possibly be modified to achieve what I want (constant movement as opposed to be controlled by the mouse) etc

Is there a simply way of doing this and would anyone have any suggestions. Would really appreciate any help.
