Bulk Updater Settings.
iaffpro_bu_run_bulk_updater( $batch_size );
Accepts one parameter,
$batch_size which is an
integer. The default batch size is 20 which can be filtered using
Image Attributes Pro
version 4.2 and later varies the images per batch based on the server conditions. However, if you override the default batch size using
iaffpro_bu_batch_size filter, the variable batch size is not used.
// Run Image Attributes Pro Bulk Updater iaffpro_bu_run_bulk_updater( 25 );
