How do I import Category Image programmatically in Magento?

I need to import category images from the filesystem in a synchronisation system. For product images there is an API provided by Magento that let me work with images (move, create开发者_开发知识库, delete, etc.) Is there such an API for category images? If not what is your advice?

Upload the image to /media/catalog/category and reference the image filename in your API call.

SOAP API for category.update ‘image’ => ‘filename’
