+ * An Image wrapper component that autosizes itself to the size of the actual image.
+ * You can always override by passing a width and height in the style.
+ * If passing only one of width/height this image component will use the actual
+ * size of the other dimension.
+ *
+ * This component isn't required, but is provided as a convenience so that
+ * we don't have to remember to explicitly set image sizes on every image instance.
+ *
+ * To use as a stand-in replacement import { AutoImage as Image } and remove the
+ * Image import from react-native. Now all images in that file are handled by this
+ * component and are web-ready if not explicitly sized in the style property.
