You should be able to set the max-width characteristic of your
external graphics, and you should be able to work out the available
width from the page width, left-margin, and right-margin plus
actual-start-indent and actual-end-indent at the current point.

As I read section 12.5.2, you should also be able to use:

(make external-graphic
      entity-system-id: "graphic.eps"
      display?: #t
      max-width: (display-size))
