Experienced in HTML and CSS, but fairly new to Joomla and PHP, I needed to build a site for a photographer. My client wanted to edit her own photo captions without adjusting XML files and also required sleek slideshows that showed off the photos. I found Ignite Gallery really easy to use and the client is very happy with the aestetics and that the captions can be changed through Joomla.
Initially I had a problem that Ignite Gallery was conflicting with a menu I was trying out, but my support request was answered extremely quickly and I was informed of my different options to resolve the issue. Now everything is working fine!
Anyway, this is an amazing, attractive and easy-to-use extension. I have already made a space for it on my next site!
