I'm an amateur photographer, and I needed a way to build galleries and display my pictures on the net. I already had a hosting account with Instafree, so I had a look through the Softaculous CMS installer for a gallery management package. After a few false starts, I found Piwigo and was pleased to see that it was free. I installed it, and started to load pictures. So far I'm pretty pleased with it, and I'm working through the plugins and features to do a bit of tuning. You can see my galleries by clicking this link -
