PNG transparency test

PNG transparency test: "PNG transparency test

PNG (Portable Network Graphics) is the only Web graphic format offering alpha transparency. Here you can test, whether your browser supports this amazing feature.

There are more comprehensive PNG support tests on the web (see PNG test images), unfortunately they let you only guess what your browser does wrong. This test on the other hand consists of a single test image and a serie of reference images showing common rendering errors. You can compare how your browser renderes the test image with the reference images and easily see what it does instead of rendering the image correctly."
