docs: Fixed broken image link, and broke long lines in code samples

While I had gridview open (per the bug), I also checked the other
files in that directory for broken image links (in case this stemmed
from a doc reorg). I didn't find any broken images, but I did find
a couple of code samples that unnecessarily had horizontal scroll
bars, so I fixed those.

See first comment for doc stage location.
