Image Presets enable assets to dynamically deliver images at different sizes, in different formats, or with other image properties there are generated dynamically. You can choose a preset when you export images, which also reformats images to the specifications that your administrator has specified.
In addition, you can choose an image preset that is responsive (designated by the RESS button after you select it).
This section describes how to use image presets. Administrators can create and configure image presets.
Image presets must be published before they can be used. See Publishing Image Presets.
