I seem to get these randomly and I can only surmise that it happens everytime an image is uploaded to the site. (which would naturally be watermarked per your add-on)

Database error in vBulletin 4.2.0:

Invalid SQL:

The issue that I have is that it's always generated by an "Unregistered" user, which on our site has no permissions to post, thus no permissions to upload images. The IP address listed is also always from some foreign country. (.fr in the example above)

My biggest fear here is that this script can be used to compromise the security of our server and that is no good.

Can you please explain why these errors occur and how they may be corrected?
