Allow exclusion of images via class / ID

[E-VANCE]

We'd need to exclude images from processing with Gumlet via class / ID in addition to the existing options (Image URLs & post type) as these do not work in certain cases...

Please consider adding this feature.

Also see WP Rocket's lazy loading exclusion rules, they handle class-exclusions and that might provide a good starting point?

Thanks for the suggestion — class/ID exclusion would be a useful complement to the existing URL and post-type options, especially when image URLs change (resized variants, srcset, query strings).

We are not planning this for the current release. In the meantime, images with fetchpriority="high" are already skipped, and you can exclude specific URLs or entire post types from the plugin settings.

We will keep this open as a feature request and revisit if more people need it. Appreciate you taking the time to write it up.
