Get imagen from item or download imagen from item

the imagen of spotify and kodi is a variable URL my idea is if I Have a ITEM with imagen how can get or download It and after it show imagen like Src in XML

Ok, we are back with the same thread again…

What does the variable URL looks like?
Once you have the URL, use the executeCommandLine action with wget to download the image into your static folder (On openHABian: /etc/openhab2/html` then the file will be accessible by your UIs.

Give is a go and come back with your code

Wget is available for Windows. Google it and install it.
