In this case, I would also run ImageMagick's -trim on it, similar to what I did in this thread (Posts #6-7):
Converting pdf to png images
That would crop out that surrounding whitespace.
(This is the one and only time I unzip an EPUB manually, run conversion on the images, then drag/drop the corrected images back into the EPUB, then reopen in Sigil.)
