Hi I hope someone can help me with centering the Category Image .. on my page.

Site is http://www.broomebeads.com.au/index....index&cPath=18

I already have the product info centred module for my product pages and I have tried playing with the css .categoryImg img I have tried text-align:center and margin: 0 auto and was hoping some kind person would know. The only way I can move it is with padding and all my category images are different sizes.

Thanks
