I belive this functionality would raise the bar for the Photo Galleries and make them more alive and exciting for the viewer.

Hello folks!
I’m happy to say that loop option is already in the widget!
You can find it in your widget Layout tab → Slider/ Thumbnails/ Columns Settings → Loop
Please let me know what you think about the update!

Hello friends,
Loop option and Fade transition are added to the widget! 
Here’s where you can find these options for Thumbnails and Slider layouts:
- Go to your widget Layout tab
- Choose Thumbnails/Slider Settings section
- Find Loop and Animation Type options
You can always check these features in action in our Photo Gallery online demo (Responsive Photo Gallery widget for your website (free and easy)) !
And your feedback is highly appreciated
