Automatically refreshing images?

I am not very familiar with angular, but is there an easy way to have automatically updated images, say every few seconds from a static url (e.g. http://camera1/image.jpg)?

That’s a missing feature of the standard Image widget… It was planned but never implemented. I’ll put it back on the todo-list - maybe open an issue on GitHub?

Done. https://github.com/openhab/org.openhab.ui.habpanel/issues/79
