Hi and welcome
Currently the auto-cycle is only supported for web.
This could be extended for local disk too, I will take a look.
That said, it should be working for web:
Instructions:1. Click the 'Crawler' tab of the application.
2. Browse to a location (local disk, url, feed, or drag & drop)
3. Click the Crawl button.
3. When at least one image is found, the auto cycle button is then enabled.
4. Click the auto cycle button when it is available.
5. Select the appropriate interval for wallpaper changes from the popup and OK the window.
Wallpaper should now change using the selected feed and delay.
Let me know if you are still having trouble, I will be glad to help.
Update:
There was a bug which causes the auto-cycle to stop when the application is minimized.
A fix was released.
I apologize for that, I gave you disk crawling as compensation
