Created attachment 95355 [details] patch to use the current API WebCore::writeOutput() in WebCore/platform/image-encoders/skia/PNGImageEncoder.cpp tries to access (struct *png_struct)->io_ptr which is deprecated in libpng-1.4 and removed in 1.5. The new way is to use png_get_io_ptr(). Attached is a patch that uses this function.

fyi, from the libpng manual: The png_get_io_ptr() function has been present since libpng-0.88, has never changed, and is unaffected by conditional compilation macros. so this patch is backwards compatible with pretty much every distribution that's newer than 1999.
