global custom image

Hello,

As i see there are only 2 options for Global Fields in views :

Global: Custom text -> Provide custom text or link.
Global: View result counter -> Displays the actual position of the view result

The future of Views will have:
Global: Custom image -> Provide custom image. ?

I'm still learning drupal views theming.
I need to add a custom image linked to node in a view, how can i achieve this?

Many thanks,
Blue
