# Image Handling

This document tries to give some insights into the low-level features for image handling. This includes the functionality of these classes:

- `qx.bom.element.Background` (API)
- `qx.bom.element.Decoration` (API)

Generally there are two common ways to show images in a browser: normal image elements and background images. The `Decoration` class supports both of them and automatically selects the type to use for a specific requirement. The `Background` class is a simple wrapper around the support for background images. It is mainly some cross-browser magic to fix a few quirks of some of the supported engines.
