 For convenience, minimum and maximum file sizes may be specified as a string with a suffix indicating the file size units. The `kb`, `mb`, `gb`, and `tb` suffixes are supported:
 
 ```php
-File::image()

+To validate that uploaded files are images, you can use the `File` rule's `image` constructor method. The `File::image()` rule ensures that the file under validation is an image (jpg, jpeg, png, bmp, gif, svg, or webp):

+#### Validating Image Dimensions
+
+You may also validate the dimensions of an image. For example, to validate that an uploaded image is at least 1000 pixels wide and 500 pixels tall, you may use the `dimensions` rule:
+
+```php
+use Illuminate\Validation\Rule;
+use Illuminate\Validation\Rules\File;
+
+File::image()->dimensions(
+    Rule::dimensions()
+        ->maxWidth(1000)
+        ->maxHeight(500)
+)
+```
