Is it possible to reload an image directly in the 3d view? I am trying to reload the image i use to my 3d model directly in the 3d view. From what i can understand so far you can reload bu putting the mouse pointer over the material panel and pressing alt+R or press"reload current image from disk", however that is very frustrating to be forced to open that panel everytime,especially since i worked with maximized 3d view and my custom made pie menu, is it possible to write your own shortcut for this, or is it some kind of script that can fix this?
An ugly method (but possibly enough for your needs)
If you just have a few images and they aren't giant. You can reload all images, (The update becomes visible after moving 3dview around a little)

import bpy

bl_info = {
    "name": "Refresh Images",
    "version": (0, 1),
    "blender": (2, 76, 0),
    "description": "Refresh images",
    "category": "3D View"
}


class SimpleImageUpdater(bpy.types.Operator):
    """Tooltip"""
    bl_idname = "view3d.refresh_images"
    bl_label = "Image Refresher"

    def execute(self, context):
        for img in bpy.data.images:
            img.reload()
        return {'FINISHED'}


def register():
    bpy.utils.register_class(SimpleImageUpdater)


def unregister():
    bpy.utils.unregister_class(SimpleImageUpdater)


if __name__ == "__main__":
    register()


Auto updating version of the execute function

def execute(self, context):
    for img in bpy.data.images:
        img.reload()
    bpy.ops.wm.redraw_timer(type='DRAW_WIN_SWAP', iterations=1)
    return {'FINISHED'}
