+# External images
+
+This feature automatically downloads images locally if an external image URL is specified in src.
+This, like the other features, works at build time and does not affect development speed.
+
+## Usage
+
+```jsx
+
+```
+
+When in production, it will be rendered as follows. (Only important parts are shown.)
+
+```jsx
+
+```
+
+During development, as with local images, no optimization is performed.
+Also, no downloading to local is performed.
+
+```jsx
