1) Social Media:- This is the best way to promote product your product online now. You may use facebook, twitter and other social media sites to promote your product to niche. In fact linkedin is also becoming the best way for product promotion now.
2)Photosharing Sites:- You may display your product info and photos on different photo sharing sites in an attractive way
3. I would create a sustainable way to generate traffic by creating a following.
- Have a blog with banners leading to the product website - Bring value through article/video/audio as often as possible - Reach out to leaders in that target market - Comment on their blog and strike a conversation - Offer them to write on their blog
