If you want to show the image in WebGrid, you can do something like,

HTML

grid.Column(format: (item) =>
                {
                        return Html.Raw(string.Format("<text><img src="\"{0}\"" alt="\"Image\"/"></img></text>", Url.Content("~/Content/images/preview-photo.gif")));
)

Why make things difficult, if you can do it easily ! :)
