Can't reach the image corresping to my srcset


I’m trying to use srcset to change image while I’m resizing my window.

Here is how I’m displaying my images :

  <?php $images =  $page->medias()->toFiles();
      foreach($images as $image): ?>
        <a href="<?= $image->url() ?>"><img src="<?= $image->url() ?>" alt="<?= $image->alt()?>" srcset="<?= $image->srcset() ?>"></a> 
    <?php endforeach ?>

I set srcset value in my confign like this :

'thumbs' => [
    'srcsets' => [
            'default' => [380, 880, 1080]

I have verified my media folder, if the images thumbs are created, it’s seems good :
Capture d’écran de 2020-03-19 20-46-05

But when I’m resizing my windows, the sourceset doesn’t change :

@QuentinJuhel Why should the srcset change? It will always include these three sizes. The image itelself, however, will change and you should be able to see that in your network tab.

Ok I see in the table neatwork that’s working ! It’s fine
The problem come from my inspector. I restart my browser and it’s diplaying now.

By “change” I meant that I didn’t see my source images in the srcset when I’m inspecting my web page.
