There are three different scripts in the attached zip file.
Wxdrought2.php just displays the CPC's Long Term Drought Indicator Map.
Wxdroughtmongif12.php displays the past 6 week, the past 12 week, and the past 12 month drought history via gif animations.
Wxdrought3.php contains the CPC's home page graphics display with mouseovers and links. I just created the last one this morning. All three currently validate at validator.w3c.org. My preference is for links to open in new tabs, and I've constructed wxdrought3.php along those lines.
The scripts are intended for use in the SaratogaWx templates.
Enjoy!
Edit 2017 April 19: Zip removed. Current individual scripts are obtainable using '?sce=view' then 'Save as...' as my preferred method of distribution.
