nil img attribute at seal head "十" in swjz.xml

[mpsuzuki]

In swjz.xml, most seal head entries refer the image files, like,
嘏
but, there is an exception. "十" is described as
十

looking at
http://archive.wul.waseda.ac.jp/kosho/ho04/ho04_00026/ho04_00026_0003/ho04_00026_0003_p0009.jpg
we can understand as the image file for "十" would be "088b-07".

But crawling the image files at kanji-database.sourceforge.net, it seems that
there is no "088b-07.png" (or "088b-07s.png"). I guess, XML was manipulated
after the cropping work, and the author could not find the corresponding seal
image, and leave img attribute as "nil". I think, the missing image file should
be supplied, and the nil-attribute problem should be fixed. How we can contribute
the missing image file?
