I've tried most of them over the last few years and Slideshow Wallpaper HD is easily my favorite. I love how you can also have the images auto pan
I have game wallpapers/cars cycling on my phone. If you're like me and have alot of pictures you'd like to use use as a wallpaper or just wanna see them more frequently - I highly recommend Slide Show HD Live Wallpaper. I have it cycling in short time intervals while panning across my home screen and I love it. I haven't noticed any significant impact on battery life in the couple years i've been using it.
I have game wallpapers cycling on my desktop and phone and after playing this game I naturally added a pile of NieR art to both. Ran into these today for anyone interested.
Also, if you're like me and have so many awesome pictures you cant decide which to use as a wallpaper or just wanna see them more frequently - I highly recommend Slide Show HD Live Wallpaper if you're on the Android platform. I have it cycling in short time intervals while panning across my home screen and I love it! Game on all!
