New BridgeDB GimpCaptcha should be case insensitive (or should say it's sensitive)
Sherief reports that the new captcha is case sensitive (it is), whereas the previous (re)captcha was not (the check was done remotely, remote resource must have implicitly done case-insensitive check.)
I assume this is the relevant line: https://gitweb.torproject.org/bridgedb.git/blob/HEAD:/lib/bridgedb/captcha.py#l206
Should probably either do a case-insensitive comparison, or should tell users it's case sensitive (I suppose the former makes more sense.)
To upload designs, you'll need to enable LFS and have admin enable hashed storage. More information
