I just installed this module today and can't get a image to show in the captcha area of the form. I'm using the built in fonts that cam with the module. I have it enabled for the user registration form. I can't see the example either on the modules example page. Here's my setup:
Drupal 6.19
PHP Version 5.2.14
Linux Apache 2.0

GD enabled

GD Support enabled
GD Version bundled (2.0.34 compatible)

thanks

Hi,

What happens when you request the CAPTCHA image directly: look in the markup for the url of the image (it should be something like http://www.example.com/image_captcha/20/1292115581) and copy-paste this in the address bar of your browser. Do you get an error message and if so: what message? Do you get an empty white "page"? Can you do "save page as" and does that result in a non empty file?

Do you have a lot of other modules installed? Do you have custom modules installed?

I have this same issue at memphistrainrevue.com. When I do the actions posted by soxofaan, I get an empty white page. I can savepage as and get a white jpg. When I look at firebug, there is html markup with an image tag below:

<img src="http://memphistrainrevue.com/image_captcha/2522/1292017055" alt="http://memphistrainrevue.com/image_captcha/2522/1292017055">

I have the same issue at www.memphistrainrevue.com. When I enter the url into new window I get white page. When I save as I get a white jpg.

same as me. the image does not appear also.
if you can give any hint, what module would lead to this problem, i can try to disable it and let you know.

cause i have about 80+ module need to check.

I am not getting a white page. I am getting a white page with a 240x80 px box of "snow" with no letters. Here's the html I pulled from the page:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD>
<BODY><IMG src="http://www.highcaliberpc.biz/image_captcha/43/1296923895"
width=240 height=80></BODY></HTML>

I have tried both .ttf and .fon fonts.

@HighCaliber, that was exactly the same problem I had. Thank you for posting your solution! And I had been going around looking at all my modules for closing tags as suggested by another thread.

I have the same problem. When I open markup for the url of the image in new tab, I get the following message :
The image “http://localhost/site/?q=image_captcha/240/1351835176” cannot be displayed because it contains errors.
Any solution ?

@qami: you're probably having a different problem. I guess another module on your set up is breaking the images. see http://drupal.org/node/271883#comment-889163 for more info
