Placing the image on a urxvt is described in its man page. I got tired of having to make 1024x768 images when the originals were mere vertical strips to begin with. Thus the need to understand image placement in Eterm, and subsequently urxvt.
Here's a quick howto, check out the screenshot in http://shedied.deviantart.com/gallery/#/d31qf54
. The term on the left is what you get, the default 100% fill-up-the-back-willya, by specifying
urxvt -pixmap name-of-image.jpg (or png)
The image on the right, the DKNY photoshoot with the two very familiar models, uses geometry:
urxvt -pixmap name-of-image.jpg;30x85+100+100
30x85 is a rough percentage of the size relative to the terminal, so 30x100 would make it stretch to the full height, but leave it at 30% of the terminal width. The +100+100 pair tells it to pin this image from the right and from the top; iirc these are percentages as well. Putting +0+0 would put this at the far left and obscure the text of commands and their output. You could do a lot more effects following the man page; or simply place a logo and keep it lean.
You can make the appearance 'permanent' in .Xresources, in our example using the
I prefer transparent pngs when I can use them. Don't forget to escape the ; with a \ if you're entering the urxvt on a command line.
