Hi Frank,
I see you're using the WD/AJAX/PHP template with the alternative ajax-dashboard (very nice!).
The WD conditionscolour.jpg is not used directly by the template with either version of the dashboard, but the creation of it by WD needs to be enabled in order that the WD tag %conditionscolourword% can be used by PHP in generating the initial page. The ajaxWDwx.js JavaScript which provides AJAX updates to the word uses the data values from clientraw.txt to compute and display what conditions word should be displayed. It is based on the same algorithm used in WD, and the words are contained in the script. Your version of ajaxWDwx.js doesn't seem to have the computation for the conditions color, so I suggest you
download, customize and install the current version (Version 2.18 - 20-Mar-2008) which includes that processing.
Best regards,
Ken
