 Hello,

 Since wp_postmeta table gets so big, and most users just upload and delete
 and change themes/media sizes and reload and change again, etc. sooo often
 …could someone at WordPress just give a customizable function to handle
 data in that table? Specifically for images …

 I´m using a filter to prevent storing exif and iptc metadata in the same
 meta key for sizes (_wp_attachment_metadata):


 add_filter( ‘wp_read_image_metadata’, ‘__return_false’ );


 but I had to delete manually all data that was previously added by default
 …and the same for unused images´ sizes.

 I guess wp-includes/media.php points something about this but I have no
 idea about unserializing, query for specific data, filtering results,
 deleting it, serializing again and restoring to db …I´m affraid this tasks
 have to be done manually by users with no code knowledge …

 Hope someone could write a custom php script for this.

 Thanks,

 Julia
