Simple answer is.....
;- Create some x, y data to plot
x = indgen(100)
y = x*x
;- Create some image from random numbers
image = randomu(3, 100,100)
;- Get the dimensions of the image
sz = size(image, /dimensions)
;- Set the size of the window you'd like
windowXsize = 500
windowYsize = 500
window, /free, xsize=windowXsize, ysize=windowYsize
plot, x, y
;- Top Right Corner
tv, image, windowXsize-sz[0], windowYsize-sz[1]
;- Bottom Left Corner
tv, image, 0, 0
;- Top Left Corner
tv, image, 0, windowYsize-sz[1]
;- Bottom Right Corner
tv, image, windowXsize-sz[0], 0

Essentially the syntax is...
tv, image, X Position, Y Position
