The files in the distribution .zip packages should be uploaded while preserving the subdirectory names and contents. The main scripts should be in the document root of your website, with the subdirectories preserved. When finished, the document root will have the .php, .js, .css, .txt, .html files,
./ajax-images/ will have .gif, .png, .jpg files
./cache/ will be writable by PHP and used to store data from forecast, advisory, and other scripts
./forecast/images/ will contain images used by the forecast program
I highly recommend using
FileZilla for doing the uploads.. It's free, and works on Macs too
