In reply to Joseph Dickson.

The new feature is based on the dimensions of the uploaded image, not the file size, so videos and PDFs are unaffected.

Of course, if someone DID need to be more granular for other image types, it’s filterable (big_image_size_threshold), so the feature is infinitely configurable.

Naturally, reducing the dimensions of an image also tends to reduce the filesize (sometimes drastically), which is a big improvement, regardless of what the wolf thinks 😉
