[PHP-DB] Problems in creating image

[Ruprecht Helms]

Hi,

I want to insert a securityimage within a registrationform. 
Unfortunately the securityimage-scripts is putting out errors.
Actualy I have the whole project that include also these scripts on my 
local host under /srv/www/htdocs/<projectdir>.
What can be wrong because the script only says that it cant be displayed 
because there are errors in the script. What
errors that are not mentioned.
The database "Moneysql1" mentioned in the script is stored localy.

As Attachment the script.

Regards,
Ruprecht
