I do exactly what you mention, overlaying 1,2 or 3 images on a graph page
using tv and the ps device. You do set the !p.multi correctly? Here's what
I do (some of the commands are other procedures I've written):
;this is the procedure to put an image into the graph window:
;first, you add [1,0,0,0,0] to !p.multi, forcing it not to erase the window
;on the second plot command. then, you use the x,y,xsize=,ysize=, /inches
;keywords to specify that you want the image in a certain place and a certain
;size on the plot window.
;;;;;;;;;;;;;;;;;;;CAN YOU BELIEVE IT? I ACTUALLY DOCUMENTED SOMETHING!!!!!!;;
pro graphpic,edata,graphdata,imagedata
back=!p.multi
!p.multi=back+[1,0,0,0,0] ;this disables clearing plot window.
pgsize, 15 ;this size seems good (in mm, square image).
plot, edata,graphdata,xtitle='Energy (eV)',ytitle='Counts',$
xstyle=1,yrange=[0,1000]
tvscl, rebin(imagedata,186,186),3.7,3.7,xsize=1.8,ysize=1.8,/inches
arrow, 1.8548,550,1.8567,850,/data,/solid
psoff
!p.multi=back
end

I'd use a program such as IMDISP:
http://www.gumley.com/PIP/Free_Software.html
that allows the image position to be specified by a POSITION vector or
the system variable !P.MULTI, e.g.,
entry_device = !d.name
set_plot, 'PRINTER'
!p.multi = [0, 3, 1, 0, 0]
imdisp, dist(256)
imdisp, dist(256)
imdisp, dist(256)
device, /close_document
set_plot, entry_device
IMDISP has other advantages as well:
- Supports WIN, MAC, X, CGM, PCL, PRINTER, PS, and Z graphics devices,
- Image is automatically byte-scaled (can be disabled),
- Custom byte-scaling of Pseudo color images via the RANGE keyword,
- Pseudo (indexed) color and True color images are handled
automatically,
- 8-bit and 24-bit graphics devices are handled automatically,
- Decomposed color settings are handled automatically,
- Image is automatically sized to fit the display (can be disabled),
- Color table splitting via the BOTTOM and NCOLORS keywords,
- Image aspect ratio customization via the ASPECT keyword,
- Resized images can be resampled (default) or interpolated,
- Top down image display via the ORDER keyword (!ORDER is ignored),
- Selectable display channel (R/G/B) via the CHANNEL keyword,
- Background can be set to a specified color via the BACKGROUND keyword,
- Screen can be erased prior to image display via the ERASE keyword,
- Plot axes can be drawn on the image via the AXIS keyword,
- Photographic negative images can be displayed via the NEGATIVE
keyword.
Cheers,
Liam.

Whoops! Of course, there would be a CLOSE_DOCUMENT
in there somewhere. :-)
thisDevice = !D.Name
keywords = PSWindow(/Printer, /Landscape, Fudge=0.25)
Set_Plot, 'PRINTER'
Device, Landscape = keywords.landscape
Device, _Extra=keywords
!P.Multi=[0,3,1]
TVImage, image1, /Keep_Aspect
TVImage, image2, /Keep_Aspect
TVImage, image3, /Keep_Aspect
!P.Multi = 0
Device, /Close_Document
Set_Plot, thisDevice
Cheers,
David

Lot's of things don't work right in the PRINTER device. :-)
I'd do something like this to get three images centered
on a landscape page of output:
thisDevice = !D.Name
keywords = PSWindow(/Printer, /Landscape, Fudge=0.25)
Set_Plot, 'PRINTER'
Device, Landscape = keywords.landscape
Device, _Extra=keywords
!P.Multi=[0,3,1]
TVImage, image1, /Keep_Aspect
TVImage, image2, /Keep_Aspect
TVImage, image3, /Keep_Aspect
!P.Multi = 0
Set_Plot, thisDevice
You can learn more about how the PRINTER device works

Steve,
I can do it with the 'PS' device. I am now trying
to add 'PRINTER' device support.
