[racket] Slideshow could not load big PNG

You mean "MB" instead of "KB" below, right?

Are you running in DrRacket? Then you may be hitting the
DrRacket-imposed memory limit as configured by the "Limit Memory..."
item in the "Racket" menu. If you're in DrRacket, does raising the
memory limit help?

Otherwise, I am not aware of a limit on the size of bitmap images other
than memory, but we can investigate further if that's not it.
