I have a photo of me 18kgs lighter on the fridge. I had relegated it to the side where I couldn't see it, because it just annoyed me every time I saw it! I think I might move it back to the front for motivation :D.
My sister just sent me this link. It is intended as a weight management motivator but it could also be used to increase or decrease the girth size of anyone whose photo you upload ;)
