Hi,
I have added the option to associate image categories through both the image uploader and the "edi image" sections.
In addition to this, there is now a field where you can enter keywords to associate with your images. Eventually, these keywords will be used in a global search function.
I will be automatically updating categories for images already listed in the spotlight and marketplace. At present, your existing images will not have an associated category.
More coming soon.
