We are experiencing odd artifacts with web pages that contain GIF files with transparency. This was not an issue last March when we used your service.
Consider this sample web page:http://howardknight.net/test/giftest.html
. That page contains a 200x150 gif with a 25 pixel strip of transparency along the top and along the bottom of the GIF. The resultant PDF is attached. Notice the two grey lines.
For what it's worth, I also attached the GIF file.
This is pretty much a show stopper for us.
