You ask me for the images I want to use.

I have noticed something strange on the "maskedhostspot" example .... *confused*

Open your example http://krpano.com/examples/maskedhotspot/index.html , zoom out a little to make more visible the mistake, then pan left or right... when you arrive between 65º (depending of the FOV) the "maskedhostspot" seems to "loose his mask" and becomes visible *attention*

I also noticed that distorted hospot does not apply correctly on Pannini projection...

I have made an example using your image cave1d.jpg as the Pano, a cropped image from your first uploaded image (image1 + image2 + mask = result) as the distorted hospot and the spotmask.png from the example made by Klaus (the car). I have proceeded as Klaus explain.
Here is the result : http://andorra360.com/test/ForumKrpano/lorth22/

How do you know it for be in the correct place ?

• use cube faces
  
  
• the changing area should be in one cube face
  
  
• crop out the modified/different area out
  
  
• important - note the position and size of the cropped area
  
  
• then calculate the position and size for the hotspot:
  
  • some explanations first:
    
    • the internal space in krpano for distorted hotspots is 1000x1000
      
    • that means a hotspot with a size of 1000x1000 covers the same area like a cube face
      
    
    
  • now with the noted sizes about the cropped area the position and size of the hotspot can be calculated:
    
    • hotspot.width = area-width * 1000 / original-cubeface-width
      
    • hotspot.height = area-height * 1000 / original-cubeface-height
      
    • hotspot.ox = area-x * 1000 / original-cubeface-width - 500
      
    • hotspot.oy = area-y * 1000 / original-cubeface-height - 500
      
    • the "hotspot.edge" must be set to "lefttop" for these calculations
      
    
    
  • finally the ath/atv position of the hotspot must be set to move the hotspot to the correct cube face:
    here are the positions for the cube sides:
    
    • front: ath="0" atv="0"
      
    • right: ath="90" atv="0"
      
    • left: ath="-90" atv="0"
      
    • back: ath="180" atv="0"
      
    • up: ath="0" atv="-90"
      
    • down: ath="0" atv="+90"

• http://img17.imageshack.us/img17/7056/cave1d.jpg as the pano after converting it to cube.
• http://img36.imageshack.us/img36/9549/cave2.jpg as masked distorted hotspots after converting it to cube.
• a cropped image from your first uploaded image (image1 + image2 + mask = result) as masked distorted hospot (I have named it "gravures")
• and the spotmask.png from the example made by Klaus (the car)

• It seems that each distorted hotspot needs to have his own mask. even if the mask is the same mask for each hotspot. I have tried to mask each hotspots with the same plugin as mask but it does not work. ( in the example above I use the same mask file for each hotspot )
  

• It seems that, when fisheye is used, distorted hotspots are not "well distorted"as they are when normal projection is used. You can notice this yourself on the example above: enable a cube button and disable his mask, then switch between normal view and fisheye view... In normal view the cube hotspot match perfectly with the background... In fisheye view the cube hotspot match near perfectly with the background but there is little differences.
