I have a piwigo librare migrated to 2.8.6 and found this new feature with multiple formats very interesting and helpful to shrink the "visible size" of my photos. But I was wondering how to migrate my existing library to the multiple format one without downloading and uploading all assets.
Is there an easy way to do this? A batch? A workaround? Something I miss?
Thanks in advance.
Piwigo version: 2.8.6
PHP version: 5.3.17
MySQL version: 5.5.54
