The exception happens when you use PNG files that are smaller than 88 bytes. It's a bug I've fixed already. Please upgrade to XML Graphics Commons 1.3.1. See http://xmlgraphics.apache.org/commons/changes.html#version_1.3.1 Or you can just upgrade to FOP 0.95 final which should be available from the download mirrors within the next few hours. > Does FOP support the linking of images with transparent background?

Not out of the box. The easiest, as you seem to have done, is rewriting the PNGs to become transparent. It would theoretically be possible to implement an extension attribute that lets you specify a transparent color for an image that FOP would try to use.
