I am specifically asking for a D7 site, however I wouldn't mind know for D8 as well.


  1. Save an image in Photoshop as a progressive image.
  2. Upload this to an Drupal image field that utilizes image styles.


When doing this image styles creates a new image, is the new image still progressive or is there something I would need to configure to make sure that image styles does this automatically?

Basically Drupal does not change that kind of attribute on an image. But I thinkg you can check this way : 1- Make a very large image with Photoshop ; 2- Save it without making it progressive ; 3- Upoad it on the website and try displaying it.

NB : Very large image because for this test you want to make sure the image will display slowly.

4- save your image again with Photoshop, making it progressive this time. And then : 5- Upload the new one ; 6- Try to display it in a new tab and compare. Certainly you will see if there is a difference.

That's what I would do....

    Is it even going to matter for image styles that crop down to 500x500 or smaller? Jun 15, 2017 at 20:34

    You may try the same method and crop the second image and see the difference Jun 15, 2017 at 20:41
