I'm believe I'm looking for a slideshow photo viewing app. Let me explain, I have a project where I need to display information digitally and without any maintenance or power. I figured e-ink is the best technology and if I can find a slideshow program I can rotate the images (which contain graphical information) every few minutes and the battery life should last for days.
Another approach might be converting the images to a PDF document. How do you then automatically rotate through the pages of that PDF document?
Appreciate any suggestions
