I"ve forgotten how to do this. I actually have images where I have an
image mostly transparent in front of my object. But it's not working now.
box{<0,0,-0.0001>,<1,1,-0.0002>
texture{
pigment{ image_map {jpeg "w_myimage_gr.jpg"
filter all 0.9999
map_type 0 once }
}
finish{diffuse 0 ambient 1}
}
scale 45*<320/400,1,1>
no_shadow
translate -39*z-23*x+54*y}

Screen.inc may be the easiest solution.
In any case, we'd probably have to see your camera declaration to figure out
what's wrong (unless the problem isn't the position of the image, but the
appearance).

Okay thanks. but what worked was making a GIF and then:
box{<0,0,-0.0001>,<1,1,-0.0002>
texture{
pigment{ image_map {gif "w_mygif_gri.gif"
//filter all 0.9999
transmit all 0.9900625
map_type 0 once }
}
finish{diffuse 0 ambient 1}
}
scale 45*<320/400,1,1>
no_shadow
translate -39*z-23*x+51*y}

Your image seems to be jpg. Will not work AFAIF. With png (or tga) you can
define a transparant alpha channel.
