For the aussies on the weather-watch forum, if your interested including the Sumsmart UV Alerts as seen on some of the nightly news, they can be sourced directly from the Australian Bureau of Meteorology.
The images all hide on their FTP server in the directory ftp://ftp.bom.gov.au/anon/gen/fwo/IDYGP005/.
You’ll need to first browse to this directory to then find the specific png image for your area.
For example, http://hamlynheightsweather.com/uv.php
According to my bush lawyer skills, it’s ok to pinch the content from the Australian Bureau of Meteorology, as long as you acknowledge the image came from the BoM.
