Dweeberkitty has build and packaged the latest libpng release for VL 5.8. It is in the testing repository.
libpng: libpng (Portable Network Graphics library)
libpng: PNG (Portable Network Graphics) is an extensible file format for the
libpng: lossless, portable, well-compressed storage of raster images. PNG
libpng: provides a patent-free replacement for GIF and can also replace many
libpng: common uses of TIFF. Indexed-color, grayscale, and truecolor images
libpng: are supported, plus an optional alpha channel. Sample depths range
libpng: from 1 to 16 bits.
