The MNG test-suite is designed to test the MNG capabilities of your browser or image-viewer.
The latest version of this test-suite can be found on libmng.com.
To test your image-viewer you can also download the test-suite in
a single zip-file.
Please note that implementations based on libmng-1.0.4 (or older) may not correctly display
the images on the pages that the bottom 11 rows point to, or in the worst case may even cause the application
to hang or crash!
There are 2 sets containing several test-pages: The first set is based on the <IMG> tag.
This can be used to test browsers that have native support for MNG. The second set is based on the <EMBED> tag.
It can be used to test browsers with a plugin or ActiveX control (if it supports <EMBED>) that supports MNG.
The first 8 rows (and several of the others too) point to test-samples which are based on the PNG test-suite.
This test-suite has been a de-facto standard for PNG enabled apps to test their compliance with the PNG specification.
The suite was build and is being maintained by Willem van Schaik,
one of the co-authors of the PNG & MNG specs.
He has gracefully allowed me to re-use his images to test the PNG-specific capabilities of libmng.
It goes without saying that this also shows the strong relationship between MNG and PNG!
