Setting up Image PresetsLike a macro, an Image Preset is a predefined collection of sizing and formatting commands saved under a name. To understand how Image Presets work, suppose your website requires each product image to appear at two different sizes: 500 x 500 pixels and 150 x 150 pixels. You create two Image Presets, one called “Enlarge” to display images at 500x500 pixels and one called “Thumbnail” to display images at 150 x 150 pixels. To deliver images at the “Enlarge” and “Thumbnail” size, a Scene7 Image Server looks up the definition of the Enlarge Image Preset and Thumbnail Image Preset. Then the server dynamically generates an image at the size and formatting specifications of each Image Preset. Scene7 comes with several “best practice” Image Presets that are already set up for you to use. Administrators can create new Image Presets as well. To create an Image Preset, you can start from scratch or you can start from an existing one and save it under a new name. Images that are reduced in size when they are delivered dynamically from a server can lose sharpness and detail. For this reason, each Image Preset contains formatting controls for optimizing an image when it is delivered at a particular size. These controls make sure that your images are sharp and clear when they are delivered to your website or application.
