If the caching suggestion does not work, try the following.

 this.webBrowser1.Navigate("about:blank"); HtmlDocument doc = this.wbbFinalise.Document; doc.Write(string.Empty); 

Then go to the ftp location.

I had a similar problem trying to update a locally generated HTTP page in a web browser and this fixed the problem.

The image is cached in IE cache. You must clear the cache before updating the control. Have a look here: http://www.gutgames.com/post/Clearing-the-Cache-of-a-WebBrowser-Control.aspx

got a solution .. the problem was that the cache was a simple solution was to make a new request each time.
