# search. This way, changing options doesn't repeatedly download the remote image,
# and it removes a layer of abstraction when an error happens during download
# compared to having the search server download it.
#

#

# the search MD5 created. We're not allowed to repopulate filename fields in the
# user's browser, so we can't re-submit the form as a file search when changing search
