Set all products to same price

I am having a few nightmares trying to work out how to set all items in a category to the same price for example.
If I go to Catalogue/Attibutes Controller and select one of my categories from the dropdown once there I only seem to have the option to pdate one product at a time.

Is there a way to change the price of all products in one hit.

I have intergrated gallery2 and zen cart together so the attubutes are all photo's but I can only seem to chnage the price of one photo at a time can someone point me in the right direction

Thanks

Ian
