Really sorry to hear that you lost a friend. It's never nice when someone passes away especially one so young.
There is a slight problem with your request. In order to do a reasonably good video you need lots and lots of photos. At the link you only have 19 or so and its just not enough. Also you provide no information on your friend. ie what was he like, who he was, what was he into, etc.
I would happily spend some time on this but there is just not enough stuff to use. If you can get alot more photos, some video footage (not essential but it would help) and a biog on him then its possible.
Another idea would be to ask his other friends what they thought about him. Then you could use some small quotes from these close friends.
About 5 years ago I did a video for my baby nephew who died. I only had a few photos and a few minutes of poor footage from my fathers camera to play with but here is the result:
