Is there a way to check if a folder or image has been selected by a media picker? It seems to return just the node id either way?

Here's what I'm doing:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@if (Model.Content.HasValue("galleryImages"))
{
  <ul>
    @{
    var galleryImagesList = Model.Content.GetPropertyValue<string>("galleryImages").Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);
    <h2>@galleryImagesList.ToString()</h2>
    var galleryImagesCollection = Umbraco.TypedMedia(galleryImagesList).Where(x => x != null);

    foreach (var galleryImage in galleryImagesCollection)
        {                 
            <li><img src="@galleryImage.Url" alt="@galleryImage.Name"></li>              
        }  
     }
    </ul>                                                          
}

Well I've got that sorted. But now I'm running into a weird issue where if I don't include the line break before the "if" statment, I get a cs103 error?

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@if (Model.Content.HasValue("galleryImages"))
{
    <ul>
    @{
    var galleryImagesList = Model.Content.GetPropertyValue<string>("galleryImages").Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);
    var galleryImagesCollection = Umbraco.TypedMedia(galleryImagesList).Where(x => x != null);

    foreach (var galleryImage in galleryImagesCollection)
        {                 
            string mediaType = @galleryImage.ContentType.Alias.ToString();
            <br/>
            if(@mediaType == "Image") {
                <li><img src="@galleryImage.Url" alt="@galleryImage.Name"></li>   
            } else if (@mediaType == "Folder") {
                foreach (var folderItems in galleryImage.Children) {
                    <li><img src="@folderItems.Url" alt="@folderItems.Name"></li>  
                }
            }
                       
        }  
     }
    </ul>                                                          
}
