Understanding Dynamic Media image presets

Like 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 that your web site requires each product image to appear in different sizes, different formats, and compression rates for desktop and mobile delivery.

NOTE
In Dynamic Media - Scene7 mode, image presets are supported for image assets only.

You could create two image presets: one with 500 x 500 pixels for desktop version and 150 x 150 pixels for the mobile version. 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, Experience Manager looks up the definition of the Enlarge Image Preset and Thumbnail Image Preset. Then Experience Manager dynamically generates an image at the size and formatting specifications of each Image Preset.

Images that are reduced in size when they are delivered dynamically 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 web site or application.

Administrators can create Image Presets. 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.
