Hi,
I was testing this on a clean install on my local server, and all was going well until I installed the "Display Inc/Ex Tax or VAT Prices" module. Now I get the "enable this picture" text instead of the image. I ran the captcha_debug.php, but it may as well be chinese.

Code:
captcha::__set_state(array(
   'captchaCode' => 'K97W',
   'captchaCode_length' => 4,
   'img_width' => 240,
   'img_height' => 50,

Any suggestions on what could be the problem?
TIA
