Does an existing site with Marketing Cloud enabled force this image style to regenerate images?

• Need to test on existing site before merging

Looking great!

Compare multidev to live

I compared the image resolution between this PR and one of my testing sites. The PR has a higher image resolution.

@danahertzberg This looks good to me, but do you think it would be good to update the values in the twig templates as well? I imagine that we want to keep the images the same size, but certain widths could still be updated to the correct value for the image, such as width="200" here: https://github.com/az-digital/az_quickstart/blob/main/modules/custom/az_marketing_cloud/templates/node--view--az-marketing-cloud--30-70-layout.html.twig#L86.

We definitely want to keep the widths defined in the template as to not change the layout style.

Look at imagemagick configuration for use in this case

Testing sites

• Original
• Image style change
• ImageMagick

Resulting email I'm not seeing any difference between the original and image magick versions.
