would like to invoke Picture Frame, however, although I have my settings with Picture Frame ON, there is no icon on my screen that allows me to invoke it. What happened to the icon?

The only place where the icon is to activate the slideshow (aka: make the iPad a picture frame) is from the Lockscreen. So, put your iPad to sleep (press the Sleep button once ... and briefly). Then, press it again to reveal the lockscreen. You should see that little flower icon in the bottom right of the iPad (next to the "slide to unlock" button). Press that icon and off you go!

Hope this helps.

Must've been asleep in my head! Thanks for the answer. If it were any more obvious, ... (you know the rest of it!)
Thanks again.

Glad I could help.

And, sometimes, it's the easy stuff that'll trip you up...

And, where are my manners?! Welcome to the forum. Hope you enjoy your visit(s).
