Best practise approach for artwork for iOS and Android?

I would bulk-convert all the images to a higher resolution, perhaps 
144dpi. On Mac, Graphic Converter can batch process these in seconds, 
and I am sure there are other programs that do the same on both Mac and 
Windows. Use these higher-resolution images in your project.

On mobile, use fullScreenMode "showAll", which will automatically adjust 
the display to fit any resolution and screen size on both iOS and 
Android. Depending on the original card size, some edges will either be 
cropped or empty space will be added. There are ways around this, mainly 
by displaying an image at a larger size than the (original) card size.

There was a bug in the showAll fullscreenmode when navigating cards, but 
that has just been fixed and will be in the next 9.0 release. There are 
also workarounds for this right now if you don't want to wait.

This is a quick process that doesn't take much time because you won't 
have to adjust every image.
