How to upload an image if I am using contentSecurityPolicy?

Good morning everyone

I am working on a project in laravel and install the library

Secure Headers

Everything works fine for the configuration of the css and the javscript, but I have a section of my project that I have to load images and when I try it I get the following error:

In case you can not see the image says:

  

Refused to load the image 'data: image / jpeg; base64 / 9J / 4AAQSkZJRgABAQEASABIAAD / 4QAYRXhpZgAASUkqAAgAAAAAAAAAAAAAAP / bAEMACQYGCAYFCQgHCAoJCQoNFg4NDAwNGhMUEBYfHCEgHxweHiMnMiojJS8lHh4rOywvMzU4ODghKj1BPDZBMjc4Nf / bAEMBCQoKDQsNGQ4OGTUkHiQ1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1NTU1Nf / CABEIAQQBzAMBIgACEQEDEQH / xAAbAAEAAgMBAQAAAAAAAAAAAAAABAUCAwYBB // EABcBAQEBAQAAAAAAAAAAAAAAAAABAgP / 2gAMAwEAAhADEAAAAevAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAPD1qjk1AkG8AAAAAAAAAAAAAAAAAAAAAA8PWrSkvyCqVhr9R5mMffRhljsMt0cSHns0AAAAAAAAAAAAA ...

and you are in my configuration in the secure-headers file

'img-src' => [
        'allow' => [
            $protocol.'www.google-analytics.com',
            $protocol.'placehold.it',

        ],
        'self' => true,
        'data' => true,
    ],

I upload the image with a

<input type="file" name="img">

What kind of configuration do I have to do to be able to add the images?
