This tasty new bit of info just came in from Barrie over at Compass Designs. My jaw dropped when I read it, and I want to make sure everyone else learns this as well! Did you know that Joomla! 1.5 allows you to assign folders instead of dealing with every single image in a template in the xml file? No more writing line after line of xml for every image in your template! Read all about it here.
Thank you Barrie for saving us hours and hours of work with this one!
