This is a limitation of the current `at-exp' reader. Even when `@' shifts to S-expression mode in the `at-exp' reader, the reader assumes only characters for the S-expression part. I tried to fix the reader once, but it wasn't easy, so I left it as future work. One workaround is to put the image in its own file with normal S-expression notation: ; img.rkt: #lang racket (provide img) (define img <image>) and then use it from a Scribble document: #lang scribble/base @(require "img.rkt") @img But mostly I use the style that Matthias and others suggested, which is to write expression that generate images. I usually use `slideshow/pict', so if the image is in the file "img.png", then I'd write #lang scribble/base @(require slideshow/pict) @(bitmap "img.png") where `bitmap' is the function from `slideshow/pict' that takes a filename and returns an image. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
