I am bumping this up.
To my
limited knowledge on WD fire weather, those figures up the top you have already set up. Looking at your fire weather ( which needs updating may I add...lol ) it looks fine.
Make sure it is turned on. Make sure 'Upload to web page' is ticked and also the individual image pointer. At present neither of them are updating auto.
Click test. Click ok.
File - Exit and save.
Restart WD.
If these 2 images continue not to upload once a day please post back here John and I will nudge some of our WD members

Cheers.
