Can't Create Category Without image

Hi All,

Just one quick error I noticed.

If you create a category and leave the image field blank, it spits out an error.

You have to upload an image when creating a category.

Please fix.

P.S - Awesome job on the cart, it's the most easiest cart to modify by far. Brilliant features too! Keep up the awesome work!

I recommend havign a no-image image and just using that if you have no image to use.

Yep, sorry, I just figured 

Thanks again!
