For documentation covering Image Serving and Image Rendering, see http://microsite.omniture.com/t2/help/en_US/s7/is_ir_api/index.html#Scene7_IS_and_IR_API_Home
You can get to this same page through the Scene7 Publishing System (SPS) Help.
- Choose Help > Help Contents > Developer Resources.
- Click either the Image Server or Render Server reference guide. Each goes to the same page.
Make sure to use the left navigation, since there are some extra links there (for examples, and so on).
