The defaults are Thumbnail 150×150, Medium 300×300, and Large 1024×1024. The fixed values can be changed in the admin dashboard under Settings > Media.

The magic is in get_allowed_mime_types() which calls the upload_mimes filter. That is filtering a default array consisting of keys as a non-terminated regular expression of file-extensions and the mapped mime-type as values: array( ‘jpg|jpeg|jpe’ => ‘image/jpeg’, ‘gif’ => ‘image/gif’, ‘png’ => ‘image/png’, ‘bmp’ => ‘image/bmp’, ‘tif|tiff’ => ‘image/tiff’, ‘ico’ => ‘image/x-icon’, …. } so hooking … Read more
