No, no pics I can find. Fully remove the window and frame. You are now looking at the raw wall opening. What you do is tape over the raw wall widow cut out opening so the tape overlaps over the the opening to the inside and outside. This prevents any water from leaking down into the wall if the exterior seal goes bad. If that doesn't help I will make a mock up and take pictures.
My RV (Thor) had grey putty tape for sealant. It appeared to have dissolved over the years. I removed the windows and used the black rubber type butyl instead. That stuff seems to last forever.
