Piwigo 2.4 introduces the Multisize feature which includes many technical changes, especially int the filesystem : instead of 2 or 3 version of each photo (websize, thumbnail, high-def), we now only keep on version (original) on upload and galleries directories. The consequences are :
- hotlinks on "web size" becomes hotlinks on originals
- hotlinks on HD no longer works
- hotlinks on thumbnails no longer works
To solve this, we created this plugin which tries to create or modify the .htaccess file on the root of your installation. This file contains some url rewrite rules informing your host that links to pictures had changed.
If your don't use hotlinks to your gallery you might not apply the following upgrade and remove this plugin.
