All pointing to html pages

[Shazilk]

   I installed 1.4.6 last week, after a small but solved bug issue all was working well on saturday.

Now for some strange reason any image selected calls for a non existant html page 

Warning the links below are to an Adult only website!

Example:

The first thumbnail shown on top left of this gallery: http://www.lady-cougar.com/mypics/   entitled The Purple B**** directs to http://www.lady-cougar.com/mypics/thumbnails-25.html it should direct to http://www.lady-cougar.com/mypics/thumbnails.php?album=25

I have not touched anything since saturday when it was all working perfectly and wonder has this been hacked?

Like a fool I have not backed up my database and welcome any suggestions.
