Greetings,
I'm attemping to display a PNG file, but I'm getting a "No
ImagePreloader found" error, and spending some time researching online
didn't help:

I also had the same error from FOP when trying to load a simple JPG
version of the same file, saved from GIMP.
I am a little frustrated because there is no documentation on the Apache
FOP site for helping with troubleshooting this (I did look at
http://xmlgraphics.apache.org/fop/0.94/graphics.html and downloaded JAI
1.1.3, and it appears in the classpath (see above)). I do understand
that image formats are crazily complex, but there's no simple how-to
document (that I could find) to get basic image rendering set up in a
foolproof manner...
Thanks in advance for any assistance.
