+The Image component provides the ability to render images. It is based on
+[NodeGui's QPixmap](https://docs.nodegui.org/docs/api/generated/classes/qpixmap).
+## Example
+```javascript
+import React from "react";
+import { Renderer, Image, Window } from "@nodegui/react-nodegui";
+import { AspectRatioMode } from "@nodegui/nodegui";
+const App = () => {
+  return (
+    <Window>
+      <Image
+        aspectRatioMode={AspectRatioMode.KeepAspectRatio}
+        size={{ height: 200, width: 150 }}
+        src="https://place-hold.it/200x150"
+      ></Image>
+    </Window>
+  );
+};
+Renderer.render(<App />);
+
+```
