Rev cannot open my jpeg ! - and some serious thinking

[Peter Brigham MD]

This is way outside my area of expertise, but would it be possible to  
kludge up a workaround? It the problem is not importing an image >4095  
wide but displaying it, it should be possible to import it, split it  
into two images <4095 wide by walking through the imagedata, place the  
two side by side, and display them as a group. Nasty, but at least  
allows you to see the image. The problem would be how processor- 
intensive and time-consuming would this be. Probably a real limitation.
