No 404 or page error on "not existing" cat pages.

[Naveen]

I had around 24 images on a page, for some reason I changed it to 40 images per page. For some categories, this has resulted in no second page as there were less than 40 images, however the second page still responds but shows the content of first page itself. Causing duplicate content and poor user experience.

cat108.htm?page=2
cat108.htm?page=3
cat108.htm?page=anynumber returns the page one.

I would like this to redirect to index page and not load the picture gallery.

Please do help
