Title: Problem Solving CAPTCHA plugin for cpg1.5.x
Post by: Αndré on October 09, 2013, 10:32:17 am: This plugin replaces the built-in Coppermine CAPTCHA with custom questions your users have to answer (e.g. "Write cat without an a"). This plugin doesn't include any questions. You can add, edit and delete your questions with the config button, which will appear in the plugin manager's "Extra:" field of the plugin.

I have a question,

There is possibility that a spam bot interprets an image file (png, jpg) with either a text or a number, and enter it into the confirmation box?

Regards.

Post by: Αndré on October 10, 2013, 12:26:51 pm: Sorry, but I don't understand what you're asking for.

Post by: Niecher on October 10, 2013, 12:38:48 pm: I like this plugin,

So visually I preferred to put an image to the confirmation response.

I replaced:
Code: [Select]
$question ['text'] for an image file:
Code: [Select]
<img src="example.png" align="middle" border="0" alt="" /> This image contains the answer to enter in the confirmation box.

A spam bot can know that answer, which is in the image?

Regards.

Post by: Αndré on October 10, 2013, 01:18:43 pm: I assume you're asking for a picture CAPTCHA? E.g. the picture displays a dog, house or flower and the user needs to enter this in the box?

Post by: Niecher on October 10, 2013, 01:40:18 pm: Exactly, your idea is much better even.

I had thought just a number. Images attached.

I ask because I have doubts if this is not very safe.

Regards.

Post by: Αndré on October 10, 2013, 01:43:23 pm: I don't see a reason for your request, as the built-in CAPTCHA feature of Coppermine already provides that functionality (characters instead of digits). See http://coppermine-gallery.net/demo/cpg15x/captcha.php

Post by: Niecher on October 10, 2013, 02:05:32 pm: There must be some problem somewhere, because it does not render the original captcha image.

But this is not really worrying as I can use the recaptcha plugin or this plugin.

I like your idea of a dog, house or flower. I'll think I'll do.

Thank you so much.

Does anyone have any experience whether using this yields less or more spam than reCaptcha?

Post by: Russ_ on February 18, 2014, 01:16:54 am: Well after using this for a week my spam has dropped to zero. I was only getting 4 or so a day using recaptcha, but this is great! (Hope I installed it right and people can actually leave comments!)

I don't know why this is, as this plug-in is easier to solve than the recaptcha, but I am grateful - thank you André.

Post by: chyna on October 15, 2018, 03:43:01 am: Is there any way to increase the number of Captcha characters to allow more then 5?

Post by: Αndré on October 23, 2018, 05:14:27 pm: Is this question related to this plugin or to Coppermine's captcha feature?
