[O] scale inline images in orgmode

[AW]

Hi!

If I include an image in an *.org file, let's say [[large-image.jpg]], I can 
toggle the inline image with C-c C-x C-v .

I would like to scale the images on screen in the buffer, often I don't need a 
large picture, but just a reminder, what's on the picture. Is there a way to 
scale the image on screen, something like #+ATTR: scale=0.5 ?

Regards,

Alexander
