<p>Bulk images allows you to optimize images uploaded to wordpress without creating unnecessary copies of the upload folder!</p>
<p>Warning: the plugin overwrites images.<br />
Later the plugin tries to update links to images in articles and metadata, but it may happen that these need to be recreated. Other plugins that optimize images generally duplicate all images and create complex overlays to manage their systems. This plugin is designed to keep sites with the original wordpress structure, but it may require a little more work later. But I believe this work is rewarded by better final quality.<br />
If anything goes wrong anyway you can go back with the restore button.</p>
