Image block: Where do you select the thumbnail you want to use?

I am using the image block and I see this option but can’t work out how you select the thumbnail you want to use? Do i have the wrong idea about its function?

hi

I guess it reads the presets you define in pagetheme.php

    public function getThemeResponsiveImageMap()

    {

return [ // Bootstrap 5 Standards

// 'xxxl' => '1600px', // –> will use 1920px thumbnail (non bs5 standard)

'xxl' => '1400px', // –> will use 1600px thumbnail

'xl' => '1200px', // –> will use 1320px thumbnail

'lg' => '992px', // –> will use 1140px thumbnail

'md' => '768px', // –> will use 960px thumbnail

'sm' => '576px', // –> will use 720px thumbnail

'xs' => '0', // –> will use 540px thumbnail

        ];

    }

we have them defined upon install in the theme controller.php

then the selection fields popup underneath “Thumbnails - Configurable”

That is perfect. I wondered what I was doing wrong and there was nothing in the documentation.

Thank you
