Just pick a reasonable default, I'd say. Use defines to make them easier to
change in the future.

No, since your code must check to not overflow the buffers. But yes, it may
fill the buffer without all files fitting. That will always be a risk, and it
is so in the normal Rockbox dir browser etc too.

You can use the plugin memory area for dynamic memory to use for
arrays/buffers etc, but it takes some fiddling to keep things right and I
believe that memory is already used for the grayscale lib's buffers, and I
know there's this pending patch to the JPEG viewer that can load the image
into this area instead of the sound buffer to keep the music playing while
viewing pics. Your code might need to co-exist with these things.
