Hello, I would like to know if there is a addon which a visitor to website can send a comment with the possibility to send a image attached. This comment would be moderated by a k2 administrator and displayed in the website after approval. Is there any addon that can do this? Thanks.

I'm not familiar with any addon that has this capability.

However, I think that www.joomlart.com/joomla/extensions/ja-comment-component can attach an image to a comment.
