Bulk Recreate Thumbnails (I have 2000 galleries)

I did this once before. To do it, I edited line 13 of the manage-galleries.php file (found in \wp-content\plugins\nextgen-gallery\products\photocrati_nextgen\modules\ngglegacy\admin\) to show all the galleries on a single page of the Manage Galleries screen. I had 1500+ galleries, so I changed mine to “$items_per_page = 2000”.

Then, once all galleries were shown on one page, I could select them all at once and bulk create new thumbnails.

@remotay – Although the idea presented by @postmastergs may work we do not recommend modifying core plugin code; but, we have added a hook which you can use to accomplish much the same thing as described.

Using something along the lines of add_filter( 'ngg_manage_galleries_items_per_page', 'my_callback_function' ); where the callback function returns an integer value should accomplish the same thing.

You can add this temporarily to your theme’s functions.php file or if you use a “site plugin” you might consider adding it there.

Thanks!
