gimp and blender working at the same time?

Is there a way to have open blender and gimp and use them in conjunction , like 3dmax and photoshop does?

i learnt that you can use photoshop and gimp open at the same time and , when you save the photoshop file and then you check your uvmapped texture it uploads in ‘‘realtime’’.

is this posible with gimp and photoshop ?
