Changes to the ClickableCameraImage widget

Try the code in the PTZ widget or play with this older code I had laying around which may or may not work. Maybe it is closer to what you want…

PTZ camera feed - Add-on Marketplace / UI Widgets - openHAB Community

The idea is that you create 2 different card contents, one that FADES IN when you click on the widget, and the other FADES OUT when you click on the widget or in other words, what you see before you click on the widget. You can create pretty much whatever you want with this method.

Since the widgets are based on framework 7 you can use the examples and click and play with them at this site and get some ideas on what can be done…
