You don't need SDL_image to run the examples from HTDP2e.
If you're reading the HTDP2e, right-click the rocket image, select
"Copy Image" (or something equivalent for your browser). Then, in
the DrRacket definitions window, right-click and select "Paste".
Does that help?

No the test example fails. It states to run this code after library is
loaded(haven't been able to load library) and it gives this error.
(* (image-width )
(image-height ))
and it gives this error.
image-width: name is not defined, not a parameter, and not a primitive name
meaning to me that the library isn't loaded.
Add the following to the top of your program:
(require 2htdp/image)
[There is a margin note to this effect in the Draft version of HTDP2e
Matthias referred you to -- make sure that's what you're reading.]
