If you type "libpng-1.5.15.tar.xz" into Google you should be able to find a server that offers it. But you probably don't need it. There weren't many incompatibilities between libpng 1.5 and 1.6. You should be able to rebuild the software you're trying to use with libpng 1.6. If it's failing to build, search Google for the error message you're getting; you might find a solution. Or post it here; I may have seen it before and know how to fix it.
