Im sure this is an easy fix for you knowledgable people out there..
I have added a a whole bunch of portfolio items a while ago, they have all worked fine. But recently I have added items, and the thumbnails are now being generated at a different size. I have tried re-inserting some images that I have previously used, however they are also being generated at the wrong size.
my site is http://www.silverlinecreative.co.nz
Under portfolio you will see the red logo does thumbnail isn't quite the correct size, you will see another portfolio item with the same problem.
thanks in advance
