increase picture rotation

[drimtrim]

Hello
I'd like to increase the pictures rotation. the rate is 30 seconds for one pic and I 'd like to get 5 or 10 seconds. I don't know where I can change this frequency. I changed it in "MusicBee/plugins/Theatermodel.List/settingRotation=300". I put 50 instead of 300 but nothing.
If you can help me, I'll be very pleased

Not sure exactly but if you're talking about the backgroundgallery element, I believe it might be capped at 25-30 seconds which means one picture every 25 seconds is the fastest rotation possible.
