Yes if you can prove that the images are yours then I am sure that alibaba will support you in ensuring that they are removed. Just contact them and find out.

Quoting from [mirzabros]:

A member of alibaba.com is copying my product images and publishing his selling leads while using the same.

What could be done?

Can I lodge a complaint with alibaba.com?

I think that if you contact alibaba they will help you.

I would advice that when you put your pictures on alibaba you choose the option on ther website to put a watermark on it so it is hard to copy and has your companys name on it.
