When I upload an image, WordPress stores five images in the uploads folder, including:
- Original image
- Large size image
- Medium size image
- Thumbnail size image
- 120x120px image
I know that images 1-4 are created by default via the Media Settings and setting any of them to 0 will disable the creation of that particular image size when uploading. However, I can't figure out where the 120x120px image is being generated from. I thought it might've been from my functions.php file calling add_image_size(), but there isn't any reference to that.
Is there a way to stop the creation of this unused image dimension?
