Ken, if you happen to see this, the site says
"To use it, you need to download the ec-forecast-V5-05.zip file and unzip, then upload to your website. The scripts and GIF icons are included in the zip file."
I note that there are PNG and not GIF in the download but the fact that the default in the ec-forecast.php is now GIF should there be GIF icons?
Thanks
Dale
