New Drush Commands to Identify and Compress Large Images
https://github.com/agileadam/large-images-drush
I released a simple drush command file that provides two drush commands:
large-images-list
will list the largest images (by file size) found in a directory (and its subdirectories by default)large-images-compress
will compress (shrink file size of) images and update the associated record in Drupal’s file_managed table
