I maintain a large static site built by someone else. The bulk of the site consists of some hundreds of pages each containing some structured text - 2-3 paragraphs, plus some regular information, and then a small gallery of photos. Looking at the storage footprint the photos dominate the space taken on the server. The site was expected to be unchanging, but in fact we are always adding or changing it, as better information arrives or better photos get taken. This old site is here: http://www.earlychristianireland.org.
I'd appreciate some advice before I commit to studying.
