The best why to do it is to use a DropDownListFor and then add the result into the model.

View:

<%: Html.DropDownListFor(m => m.SelectedImageType, new SelectList((IEnumerable)Model.ImageTypes, "Key", "Name"))%>

Controller:

ActionResult YourActionName(Model model){
     var selectedImages = m.SelectedImageType;
}

Use name and in your controller use form collection to collect selected values

<select id="SelectImageType" onchange='submit();' name ="image">
<option value="0">Select Image Type</option>
<%foreach (var type in Model.ImageTypes)
{ %>
      <option value="<%=type.Key%>"><%=type.Name%></option>
<%} %>
</select>

In your controller action

     ActionResult YourActionName(FormCollection collection){
         var selectedImages = collection["image"];
     }
