I am/was a Joomla newbie. At the beginning, the plugin and it's functioning looked very difficult to me. Luckily I asked the developers to install the extension for me on the website. They explained me how it worked and I could always ask for support. That was everything I needed.
Thanks to good support, I should now be able to help myself with the basics.
I used the extension to display pictures for a students organisation. Since we have a limited web space, I needed an extension that was able to link external images.
