Position, normal coordinates, and multiple images [message #87665]

This question undoubtedly illustrates my failure to understand graphic windows, etc. For an animation I'm working on I want to place two images (identically sized) side by side and leave room on the right for a color bar, on the bottom for a graphical elapsed time indicator, and on the top for other annotations. To do this, I was adapting another code that did the essentially same thing with a single image. My original code used cgImage with the POSITION parameter set to [0.1, 0.1, 0.8, 0.8] and normal coordinates for the color bar and other various annotations. Before I read the explanation of the position math (http://www.idlcoyote.com/tips/vaughan.html) I naively set the position parameter arrays for the two images I wanted side by side to [0.1, 0.1, 0.4, 0.8] and [0.4, 0.1, 0.8, 0.8] respectively which results in the second image being larger (28% of the window) than the the first (21% of the window). Before I go back to using device coordinates to place the two images, I was wondering if someone more clever than I had a suggestion for accomplishing this using normal coordinates.
