how to view whats painted in GIMP in Blender

Hey guys!..So my question is I am painting my textures in GIMP on a UV from my model in Blender. Is there a way to paint in GIMP and switch over to Blender and have it update on my model in paint mode in real time?..I saw a timelapse of a guy painting in photoshop and switching to 3ds max and it was instantly updating…can we do this in blender?..

heres the link to the video I was watching…

gottit, installed in blender and GIMP…cant get it to work…any ideas? This would be perfect…does it work with cycles?..

HAHA…got it to work and its awsome!..thx
