Hi all,

I took a stab at doing this in IDL 8.0 with the new graphics:

READ_JPEG, FILEPATH('elev_t.jpg', SUBDIR=['examples','data']), data

x1 = 100 & w = 108
y1 = 100 & h = 128

width = 0.4
pos1 = [0.1, 0.1, 0.1 + width, 0.8]
aspect = float(w)/h
pos2 = pos1
pos2[0] = 0.6
pos2[2] = pos[0] + width*aspect

im1 = IMAGE(data, AXIS_STYLE=1, POSITION=pos1)
im2 = IMAGE(data, /CURRENT, POSITION=pos2, $
XRANGE=[x1,x1+w], YRANGE=[y1,y1+h])

; Add a fancy box and lines showing the "subset" area
rect = POLYGON([x1,x1+w,x1+w,x1],[y1,y1,y1+h,y1+h], /DATA, $
COLOR='red', FILL_BACKGROUND=0, TARGET=im1)
pt1 = im1.ConvertCoord(x1+w,y1+h, /DATA, /TO_NORMAL)
pt2 = im2.ConvertCoord(x1,y1+h, /DATA, /TO_NORMAL)
p = POLYLINE([pt1[0],pt2[0]],[pt1[1],pt2[1]], COLOR='red')
pt1 = im1.ConvertCoord(x1+w,y1, /DATA, /TO_NORMAL)
pt2 = im2.ConvertCoord(x1,y1, /DATA, /TO_NORMAL)
p = POLYLINE([pt1[0],pt2[0]],[pt1[1],pt2[1]], COLOR='red')

; Save the entire window to a PDF file
im1.Save, 'output.pdf'

Sorry it's a bit long. I got all fancy with the boxes and lines. But
it looks nice.
