Can't upload product image

[johanbosman]

I'm having problems when trying to upload product images under 'Upload file option"

I receive the following errors.

vmError: VmTable #__virtuemart_products_en_gb Check not passed. Neither slug nor obligatory value at product_name for auto slug creation is given
vmError: You are not an administrator or the correct vendor, storing of product cancelled

Any Ideas?

Using Virtuemart 2.0.18a and Joomla 2.5.8
