Hey Frangollo. So here's the solution. Add this
Fixed Window58= View (the title may be whatever you want). Then there are 2 VIEW_RIGHT_WINDOWS=12110. Chage the second to 12115. Then add this:
[Fixed Window53]
file=r.bmp
background_color=0,0,0
size_mm=1024,768
window_size_ratio=1.00  
position=7
visible=0
ident=12110
render_3d_window=1
nomenu=0
window_size= 1.000, 1.000
window_pos= 0.000, 0.000

Then this:
[Fixed Window58]
file=R_R.bmp
background_color=0,0,0
size_mm=1024,768
window_size_ratio=1.00  
position=7
visible=0
ident=12115
render_3d_window=1
nomenu=0
window_size= 1.000, 1.000
window_pos= 0.000, 0.000

Names of files (file=r & file=R_R) may be whatever you want. That's it. One more thing: you should extract right side view from "cs.b757.pass.gau" and put it to your panel folder. Put your new view there too. I think I explained rather clearly. Try. It works I've checked. By the way nice photo view, but low quality. Where did you get that? Have a nice flight.

P.S.
This is my solution of adding view. May be someone has another simplier way.

I mean instead of "View" you may type whatever you want eg. "Left view", "Left rear" etc.
