I created a mask on an image that I was working on some time back. I want to use the mask again to rework that image. I exported and save the mask as a .jpeg file and I still have the original image. 
However, when I endeavour to open them, I cannot get the "Mask" to display next to the original image on the same layer as it did when I first created it. 
I read somewhere that holding Ctrl / Shift keys down at the same time would open them together but I cannot make this work. 
I can open them both as stand alone images, or as layers, but not as an Image / Mask.
Could someone please suggest a tutorial that could explain this process or perhaps give me a description of what I need to do and attach to this thread. 
Many Thanks

• Unless the mask image is bigger than the other, make the other image invisble
  
• Open the Channels list
  
• Drag one of the R/G/B channels to the (empty) list below to copy it. You can double-click it to give it a name.
  
• Remove the mask layer, make the initial image visible
