  • [Forum] A couple of questions about ImageMagick

    I have always used GD but decided to try ImageMagick as I had heard good things about it. Is it true that you can set the font with ImageMagick for using with the human verification system? And does anyone have a good setup for that or any good recommendations?

    Also, which is better to use for human verification, ImageMagick or eCaptcha?

    IMHO all captchas are very difficult to use and ineffective. I suggest you use the Question & Answer system.

      True, but all they would have to do is figure out the question and then the bots/spammers would have a field day. But I have never really deal with the Question & Answer system. Is it hard to set up and fairly effective on keeping out the bots and spammers?

        I think it probably works it's best when you have a question that is in the context of your users. Even jargon that an unfamiliar human would not know the answer to. Although even 2 + 2 = ? seems to work for many at stopping bots. That will change I imagine.

          I just looked at it and I suck at regular expressions as they are confusing to me. Looks like I'm stuck with the image verification.

            I don't think anyone uses the regular expressions when they create Questions & Answers. Just make it really simple for example:

            Enter the word "boofo" to verify you are human.

              Add a question, after saving your question, you can add anwsers.

                I read the you are not supposed to give the answer in the first part as the bots/spammers pick up on that pretty quick. The regexs is more for the capitalization or small letters scenario so it will pick it up either way.

                I have done that but I want to be able to have the answer be in whatever case they choose. I used to have a question with that setup for the registration process but I can't remember how the regex was done, as Peterska did the regex for me at the time, quite a while ago.

                  No problem having the answer right in the question, bots are not able to figure it out. Forget the regex, keep it simple.

                    The anwsers are case insesitive by default

                      So, if the answer is Iowa, it will accept ioWa, or any variation of the case? *And youi're sure on that, right?


                      Well, then I don't need the regex. I thought I had to do that for the case sensitivity. What would regex be good for then?

                        That is the definition of case insensitive.

                        Allowing for a question like: "Enter any number between 1 and 100".

                          Believe it or not, I knew that. I was just verifying it.

                          Allowing for a question like: "Enter any number between 1 and 100".

                          Can you give me an example of what the regex would look like for that?

                            ^([1-9]|[1-9]\d|100)$

                              It's still all Greek to me, I guess. You would have to have 100 separate answers for that question using regex.
