How to Build Scenes.Image

[Archangel2011]

I've done a forum search and looked around online, but I can't seem to figure out exactly how to build the scenes.image file that everyone says you need to run custom vcds.

Right now as it is, I have my vcd set up and ready to go in hammer, if I hit preview it even plays fine. Then in game when it triggers it tells me:

"Blocking load of scene from ' scenes/leaner.vcd'
Scene 'scenes/leaner.vcd' is missing!

I think the problem is that I don't have the scenes.image file in there, any help?
