Image slideshow - preferred app and speed

Hey everyone,

I have a computer that I would like to constantly be showing a slideshow of jpeg images in a loop, at a set time of about 7 seconds between pictures.

I usually prefer not to install secondary apps and programs, and stick with what comes with windows, so I was using the photos app to accomplish the slideshow. However, I cannot change the time to anything other than the 5 second default it is set to. If there are any suggestions on this matter, it would be most helpful.

In addition, I noticed that after a bit, the slideshow would suddenly stop. I changed the power settings to keep the hard drive on, and avoid sleep and screen blank, but is there anything else I should change to avoid a stalled slideshow? I have yet to check if my solution worked, but I'll post back soon enough.

Thanks!
