[Addition] Add an Image to mediafiles

[Iam-Muslim]

Aslam alaikom my brother ,

Adding image to mediafiles acts as a 5 second video You can make a static image be defined to play along with the whole video in it's own place as video 1 and video 2 ...

you can make an option to view sound waves iside the sound track

I've split this this issue as it is two separate things. See #16
