Captcha images not shown at all

[Tuto Violin]

Hi!! recently updated to 1.5.0 but captcha images are not shown I tried everything on modes (jhtml - jroute) and never works, sometime ago it was working fine but no more... What can I do?

Joomla 1.5.25 mootools upgrade enabled
PHP 5.3.8
Template: grunge (rockettheme)
Chrome

Thank you! I really love Phoca Extentions (I use maps, favicon, guestbook, gallery,) and all are the best ones!!

Thank you, Thank you, Thank you!!

Hi, try to check if some of your extension (e.g some system plugin) does not change paths to images, etc
Does it work with SEF disabled?
