A custom preview picture for ones channel

[MehfilClassicTV]

In addition to how things are now (showing random thumbnails - wich are often dark or black)
it would be nice to have a custom preview picture where one could show one's channel logo or just anything. At least as an option for the embeddable player in order for the player to blend in more nicely into ones blog or website. There could still be the Mogulus logo on top of it. Thumbs could remain as they are on the Mogulus grid if you want it that way.What do you think?

To see what I mean have a look at my old Mehfil TV channel (not live) it had this function:
