Recreating GTW's Troll Arms Hut skin

[StonemaulMidget]

Hello!

I'm recreating a skin for the Troll Arms Hut, from the extinct Great Troll War mod.
Here, I circled the canvas with a Magenta circle, and then outlined the canvas using a lime green rectangular prism.
Firstly, I want to scale the canvas' angularity on the picture, so it looks like a 90-degree square.
Secondly, I want to replicate the squared image on PhotoShop. <--The real treat.
Is there a photoshop technique about moving an image's nine points to straighten it, or a better way?

Don't worry about credits. I will look through all of GTW's creators and credit them for this fantastic piece. I do not have plans to post something like this anytime soon.

Or you could learn to texture and re-draw it all yourself join the ranks of the texturers!

Do you have the original picture?

Here's the closest thing.

That's what I planned to do. I wasn't going to simply reuse what's on the portrait.
But if the texturers have a trick up their sleeve, then show me.

Cool, thank you! Could you show me how that is done?
