How to develop smart editor to send mail with images in c#.

Hi All,

I developed a website which has a text area where user can write the text and also it has controls to upload images and document but he has to place the tag in text area to include those images. But now user want a smart editor where he can simply write the text and paste the images(or he can paste the whole contents from word document) and send the mail. Actually he want WYSIWYG mail editor to send mail. Can anybody please tell me how to develop such a smart editor or if any such third party editor available which I can use while coding in c#.net.

Any help will be appreciated.

Thanks and Regards
