Prerequisites

• I have searched for similar features requests in both open and closed tickets and cannot find a duplicate.
• The feature is still missing in the latest stable version of Elementor ( Elementor Pro )

What problem is your feature request going to solve? Please describe.

When I select a background image from the media library I can select the image size (e.g. Full, Thumbnail, Medium) etc.
But I select the background image from an ACF Field I don't have this option.
I would like to have the image size options for ACF Fields.

The same applies for Featured Images. I can select the size of the Featured Images.
