+    \brief The QDeclarativeImageProvider class provides an interface for threaded image requests in QML.
 
-    Note: the request() method may be called by multiple threads, so ensure the
+    QDeclarativeImageProvider can be used by a QDeclarativeEngine to provide images to QML asynchronously.
+    The image request will be run in a low priority thread, allowing potentially costly image
+    loading to be done in the background, without affecting the performance of the UI.
+
+    See the QDeclarativeEngine::addImageProvider() documentation for an
+    example of how a custom QDeclarativeImageProvider can be constructed and used.
+
+    \note the request() method may be called by multiple threads, so ensure the
     implementation of this method is reentrant.
