Max Last Render to Photoshop

I would like a script that takes the latest render in max and bring it into Photohop.

Script Process
1. After render is finished in 3ds max I run the script.
2. It brings the latest render from 3ds max into photoshop.
- When bringing it into photoshop it pastes the "rendered image" into the already opened document.
- It also applies a layer mask to the "rendered image" using its alpha as the layer mask image. (Essentially bringing in the render from max along with its alpha)

That's it.

Anyone able to help out with this? It's a process I do a lot when doing curves and color corrections in photoshop to make the render match the background image.
