:raisedbrow: I'm confused. Is it YOUR picture?
What do you mean by wanting the original and bigger size? I would assume the original resides on the computer of the person who took the photograph. Whether there even IS a "bigger" size on the internet kinda depends on whether they uploaded anything bigger.
If it's not yours, I'm not sure why you're trying to find a large, original size of it to "save" to your computer. If it IS yours, I'm not sure why you wouldn't already HAVE an original, bigger size.
