Migrating from Gallery and vice versa
If you're migrating from one Gallery/Pictures app to another, your shared links will stop working, unless you tell your web server where to redirect the user.
Add one of the following rules to the .htaccess file located in your ownCloud web root. Kudos to Éric Seigne.
For ownCloud 6-8.1
RewriteRule ^index.php/apps/gallery/public/(.*) https://YOURDOMAIN/index.php/apps/galleryplus/s/$1
For owncloud 8.2+
RewriteRule ^index.php/apps/gallery/s/(.*) https://YOURDOMAIN/index.php/apps/galleryplus/s/$1
For owncloud 8.2+
RewriteRule ^index.php/apps/galleryplus/s/(.*) https://YOURDOMAIN/index.php/apps/gallery/s/$1
