+### Validating uploaded images
+
+You may use the `fileAttachmentsAcceptedFileTypes()` method to control a list of accepted mime types for uploaded images. By default, `image/png`, `image/jpeg`, `image/gif`, and `image/webp` are accepted:
+
+```php
+use Filament\Forms\Components\RichEditor;
+
+RichEditor::make('content')
+    ->fileAttachmentsAcceptedFileTypes(['image/png', 'image/jpeg'])
+```
+
+You may use the `fileAttachmentsMaxSize()` method to control the maximum file size for uploaded images. The size is specified in kilobytes. By default, the maximum size is 12288 KB (12 MB):
+
+```php
+use Filament\Forms\Components\RichEditor;
+
+RichEditor::make('content')
+    ->fileAttachmentsMaxSize(5120) // 5 MB
