如何从视图向控制器发送html img 属性值？

<div class="fileupload-new thumbnail" style="width: 200px; height: 150px;">
                @if (Model == null)
                {
                    <img src="http://www.placehold.it/200x150/EFEFEF/AAAAAA&text=no+image" />
                }
                else
                {
                    if (!String.IsNullOrEmpty(Model.Sender.Logofile))
                    {
                    <img src="~/Content/img/Company/LogoFiles/@Model.Sender.Logofile" id="logoimg"/>
                    }
                }
            </div>
            <div class="fileupload-preview fileupload-exists thumbnail" style="max-width: 200px; max-height: 150px; line-height: 20px;"></div>
            <div>
                <span class="btn btn-file"><span class="fileupload-new">Select image</span><span class="fileupload-exists">Change</span>
                    <input type="file" id="LogoFileUp" name="LogoFileUp" size="19" style="opacity: 0;" data-form="uniform" required="required" /></span>
                <a href="#" class="btn fileupload-exists" data-dismiss="fileupload">Remove</a>
            </div>
