No, he's gone through quite a few changes. The biggest difference in most people's eyes would likely be that the MK9 version wears armour, and has a long skirt flap thing coming off his loin cloth.
MK1 Goro
MK9 Goro
There have been other minor changes throughout the years, like the colour of his skin and the amount/colour of scales on his back. In a few games he has 4 pecs instead of 2, that sort of thing.
The picture definitely looks like it's based on the MK9 design.
edit: lol I guess I should've expected a hundred more replies to have been made while I was writing this post. I was replying to SARFARAZ's second post. :P
