Hello rob
Glad to see a Queensland site up here here. I live near Rothwell. I can get a few of the slideshow images working using the next image button in latest Firefox. Can I suggest you use your ftp access to empty every image in the resize folder, this will force a new set of resized images to be created and I’ve found that can work at times.
As the template is pretty old now and still a j.1.5 site. When you find your preferred designer it probably is a wonderful opportunity to upgrade to a J1.7 Joomlart? powered site and perhaps a total site revamp aesthetically.
If the resize refresh doesn’t work can I suggest using JA extension manager to grab the very latest version of the j1.5 ja news module or do so manually and remove and replace the module, I feel these are the two most appropriate suggestions available
Cheers Shane
