Whenever you use a $media instance as output in a Blade view the medialibrary will generate a img tag with the necessary src, srcset and alt attributes. You can customize the rendered output by publishing the views with:
php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="media-library-views"
The following files will be published in the resources/views/vendor/media-library directory:
image.blade.php: will be used to render media without responsive imagesresponsiveImage.blade.php: will be used to render media with responsive images without a tiny placeholderresponsiveImageWithPlaceholder.blade.php: will be used to render media with responsive images including a tiny placeholder.
You may modify these published views to your heart's content.
