 image.MergeAttribute("alt", alternateText);
 image.MergeAttribute("valign", "middle");
 image.MergeAttribute("border" , "none");

 TagBuilder span = new TagBuilder("span");

 // Create tag builder
 var anchor = new TagBuilder("a");
 var url = new UrlHelper(helper.ViewContext.RequestContext).Action(action, controller, routeValues );

 // Create valid id
 anchor.GenerateId(id);

 // Add attributes
 //anchor.MergeAttribute("href ", "/" + controller + "/" + action); //form target URL
 anchor.MergeAttribute("href", url);
 anchor.MergeAttribute("class", "actionImage" );
 if (htmlAttributes != null)
 anchor.MergeAttributes(new RouteValueDictionary(htmlAttributes));

 // place the img tag inside the anchor tag.
 if (String.IsNullOrEmpty(linkText))
 {
 anchor.InnerHtml = image.ToString(TagRenderMode.Normal);
 }
 else
 {
 span.InnerHtml = linkText;
 anchor.InnerHtml = image.ToString(TagRenderMode.No rmal) + "" + span.ToString(TagRenderMode.Normal);
 }

 // Render tag
 return anchor.ToString(TagRenderMode.Normal); //to add  as end tag
 }

I know to use Html.ActionLink() to render the text link to the action.

This is the code of the ImageLink HtmlHelper extension I used.
