## Focal points

Server-side preview images are never cropped, to support a variety of apps and user interfaces. Therefore, the cropping must be done by those apps. To crop intelligently, focal points can be used to ensure a certain section of the image is always within the cropped viewport. [See this for how to let users select focal point coordinates](https://github.com/jonom/jquery-focuspoint#1-calculate-your-images-focus-point).
