It may be helpful to check the "official" test-suite for PNG http://www.schaik.com/pngsuite2011/pngsuite.html which contains also png files with transparency http://www.schaik.com/pngsuite2011/pngsuite_trn_png.html Somehow emacs ignores the transparency for image type png, see for example the file tm3n3p02.png with multiple levels of transparency. Transparency is honored for these images when emacs uses imagemagick.
