About: April 2017, php7 user use last version (3.1.x)
Did you ever want to add none picture files to your gallery ( eg. .flv, .mp3, .pdf or any data files, now also html5)?
"Charlies content" is a global solution for those files.
Add charlies_content to your gallery, install and activate via plugins administration page, and proceed your multimedia files as you do for your pictures.
Not modified but tested ok with piwigo 2.7, also 2.8. Compatible php7
This "3.1" version should be OK, now, read the README-FIRST file, but still not widely tested, so use at your own risks
It's sometime necessary to install it manually, just copy the archive content to the plugins folder. the plugin folder name have to be "charlies" or any other, but without . or -
