In general, still images are usually pretty easy to create and import into a media server. Moving images, clips, and animations, on the other hand, are a little more involved. There are many applications that can create animations, and not all media servers can read the files they create without converting them to a format that it can accept. In other words, don’t be shocked if that really cool digital animation you just spent days on rendering doesn’t play back in your media server just by dropping it into the resource folder. It may need to be converted to another format like Quicktime, AVI or Flash before it can be used.
