[TYPO3] Picture 'click to enlarge' hacked

[Rik den Braber]

Hi,

On one site I work on for a friend the 'click to enlarge' picture option
doesn't make the picture open in a new window, but instead takes the visitor
to a page on wikipedia (http://en.wikipedia.org/wiki/Script_kiddie). I did
not change anything  to make this behavior happen, so does anyone know how
or where this is caused and how to solve it?
I use typo3 3.8.1.

I hope anyone has a solution.....

TIA
