Probably not. I would expect captcha images to be either generated on the
fly or stored in a database, so there is no path to hide. Or selected on
the fly, in which case your goal is not to hide the path but to select the
path.
Given that you are going to start up Perl in the first place, I don't
see any obvious problems with our code, other than possibly a lack of
error checking on the sysread. And that the file handle you close
is different than the file handle you open.
