How could I get the correct URL of the medias image? I want to display an image which was saved with medias. I'm trying

{{ $item->image('image_key') }}

but it doesnt seem to work, it gets a URL but it doesnt display the image.

You need to pass a second parameter to that image function, which is the crop key

I have a 'desktop' crop key, also tried that,

{!! $item->image('image_key', 'desktop') !!}

but it still doesnt display it for some reason
