+        This helper function provides the simplest way to create a wxBitmap
+        from PNG image data. On most platforms, it's simply a wrapper around
+        wxImage loading functions and so requires the PNG image handler to be
+        registered by either calling wxInitAllImageHandlers() which also
+        registers all the other image formats or including the necessary
+        header:
+        @code
+            #include <wx/imagpng.h>
+        @endcode
+        and calling
+        @code
+            wxImage::AddHandler(new wxPNGHandler);
+        @endcode
+        in your application startup code.
+
+        However under OS X this function uses native image loading and so
+        doesn't require wxWidgets PNG support.
