I´ve been using this component since 2009. At this moment I´m updating my websiste, and this is the last component to update. I explain my problem.
In year 2015 I created a new website and I made a few changes to the plugin that show the photos(I don´t remember at this moment which plugin i chose but it takes several days). I chose a plugin and i made a few changes. The problem is that I updated the plugin and the component and this changes were overwritten. How can I know which plugin i ´m using in the configuration? I´ve got my previous installation with code changes.
