+### Disable Static Imports
+
+The default behavior allows you to import static files such as `import icon from './icon.png` and then pass that to the `src` property.
+
+In some cases, you may wish to disable this feature if it conflicts with other plugins that expect the import to behave differently.
+
+You can disable static image imports with the following configuration below.
+
+```js
+module.exports = {
+  images: {
+    disableStaticImages: true,
