I just created a custom module following this tut: generate-programmatically-image-styles-drupal-8
It works great but the following occurs. When I create a new node and upload the image you see that for every style I have it creates a image (like the custom module should). But when I save the node all the created images are deleted?
Is this a standard function in Drupal that can be disabled? Hope someone can help me with this.
Thanks in advance
