Description:
------------
For new users testing/experimenting with the HTML_QuickForm_CAPTCHA package and the Image function:

Be aware that the $options array, which contains your font_path , font_file and so on, is stored as Session data.

So if you are changing any of the $options values (i.e. the font file), make sure you clear your session data - i.e. close the browser, or clear your cookies, otherwise, you won't see any changes.

Also, if you are having difficulties getting your image to display, below is an adjusted version of the sample qfcaptcha_form_image.php script which echo's the session data to a text file. It was helpful for me, I hope it can be helpful for someone else.

Will this be the error for the image?

It's a bit difficult to know, without seeing the code - are you almost using the same code as the examples: http://www.11abacus.com/dev/pear/doc/HTML/QuickForm/examples/

Perhaps post your code, so we can see and attempt to replicate.

It could be a bug, or it could have something to do with PHP5. I did the work I did using PHP4.
