PNG decoding is little more than an implementation of DEFLATE and handling of the delta encoding. For your own OS you most likely do not have to be feature complete. As an example, picoPNG [1] decodes most .png images, and is only ~500 lines of beautiful C++ code. For most practical purposes, you can probably get away with much less.
