By default when after adding images to post in wordpress, 3 copies of the same images (small, medium and large) will be created automatically by WordPress. Those images will be used for thumbnail if theme supports that feature. If you are not going to use those images, then is waste of resources
- Disk Space
- Backup space
- Expensive while using CDN/Storage
After 3 years of using wordpress, I happened to find this while playing with Thesis theme, featured image and thumbnail features. I’m using W3 Total cache plugin with Amazon CDN and S3 storage. I could have saved some money by preventing wordpress from creating thumbnails automatically in file storage.
Stop automatic thumbnail creation
Just follow the steps below to stop thumbnail creation
- Login into Admin area in wordpress
- Go to Setting > Media
- Enter 0(zero) to all the fields.
- Save the Settings
To verify that go to wp-content/uploads/current year/month and upload an image from a post. Make sure no thumbnails are created. Now, I have got some cleaning to do (maybe a small script to delete those unused images will do).

Awesome! Thanks man, I am in the process of setting up S3 as CDN & your article is right on time. I’ll let you know how it works out.
