Is http://epubmaker.pglaf.org the same app the White Washers use for
uploaded files?
Some people at Distributed Proofreaders think the results are different
between the http://epubmaker.pglaf.org/ results and the WW results
published at PG. I don't believe it but thought I'd ask here before
submitting an opinion to the DP forum.
Specifically what they are claiming is that the oversized image (greater
than 800 x 1200px or 128KB) reduction for the epub and mobi formats is
different.
