Great work @DanialV . Sorry for the late response. I've looked at your commit. I think the API becomes bloated if we include an explicit parameter file. Instead what we can do is use protocols for the url. That is, specifying url as file://mnt/ex0/downloads/video.mp4 for instance, indicates a file and loads from that directory.

What do you think?

I am also interested in this. @DanialV I think the API would look better with named constructors like following:

StoryItem.pageLocalImage() 
StoryItem.pageNetworkImage()
StoryItem.pageLocalVideo()
StoryItem.pageNetworkVideo()
