URL to PDF... "Sorry, we can't process your request"

Hi:

I have added the URL to PDF link at the very bottom of the following page, but conversion to PDF doesn't work... It returns "Sorry, we can't process your request". Any ideas on what might be causing this issue?

Thanks for any help in advance.

Hi,

the error is caused by the scale_*.png images in your page. It seems that the images violate the PNG specification but still can be displayed in some software. Re-saving the PNGs could fix some problem.

Technical info:
libpng reports "Too many IDAT's found". This can be reproduced by running e.g. pngcrush

$ pngcrush -q scale_aa.png
While converting scale_aa.png to pngout.png:
  pngcrush caught libpng error:
   Too many IDAT's found
