Page not found

I don't know where I'm going wrong. Any time I try to use the examples you give all I get is "Page not found".

When trying the link http://zxx.iter.tut/textimage/title/ciao.png I can intercept this parameters in the textimage_menu function:

Array ( [0] => Array ( [path] => _textimage/image/ciao.png [title] => textimage [callback] => _textimage_captcha_image [access] => 1 [type] => 4 ) [1] => Array ( [path] => admin/settings/textimage/preset//delete [title] => Edit Preset [callback] => drupal_get_form [callback arguments] => Array ( [0] => textimage_preset_delete_confirm [1] => ) [access] => 1 [type] => 4 ) [2] => Array ( [path] => admin/settings/textimage/preset//flush [title] => Flush Preset Cache [callback] => drupal_get_form [callback arguments] => Array ( [0] => textimage_preset_flush_confirm [1] => ) [access] => 1 [type] => 4 ) )

Then I'm lost. CAPTCHAs work no probs, so it really beats me. Where am I going wrong!?

My system configuration:
Drupal 5.1
Configuration file Protected
Cron maintenance tasks Last run 3 sec ago
Database schema Up to date
File system Writable (private download method)
GD library bundled (2.0.28 compatible)
MySQL database 5.1.11
PHP 5.2.0
Unicode library PHP Mbstring Extension
Web server Apache/2.2.3 (Win32) PHP/5.2.0

Plus I have clean-urls running, no problems so far with them. I'm on a multisite install. The present "title" exists and I already tried making it all undercase (it initially was "Title"). Still nothing but a "page not found" :(

Pls help.
