Hej Jens

I am not 100% certain I understand your problem but how about something like this:

@inherits Dynamicweb.Rendering.RazorTemplateBase<Dynamicweb.Rendering.RazorTemplateModel<Dynamicweb.Rendering.Template>>

@foreach (var i in (GetLoop("ItemPublisher:Items.List"))){

  string title = i.GetString("ItemPublisher:Item.Title");
  string description = i.GetString("ItemPublisher:Item.Description");
  string link = i.GetString("ItemPublisher:Item.Link");
  string url = i.GetString("ItemPublisher:Item.Url");
  string backgroundcolor = i.GetString("ItemPublisher:Item.ImageBackgroundColor");
  string image = i.GetString("ItemPublisher:Item.Image");

  string tagclasses = i.GetString("ItemPublisher:Item.Tags.TagName");
  tagclasses = tagclasses.Replace(",", " ");

  string imgwidth = "624";
  string imgheight = "351";
  bool projectHasImages = false;
  foreach (var img in (i.GetLoop("ItemPublisher:Item.ProjectImages"))){
    string projectimage = img.GetString("ItemPublisher:Item.ProjectImages.File");
    if(!string.IsNullOrWhiteSpace(projectimage)){
     projectHasImages = true;
     break;
    }
  }
 string imagesrc = "/Admin/Public/GetImage.ashx?Image="+image+"&amp;Width="+imgwidth+"&amp;Height="+imgheight"+&amp;Background="+backgroundcolor+"&amp;Crop=0";

  <figure class="col-3-12 col-small-6-12 no-p no-m hover @tagclasses">
      @if(projectHasImages){
      <a href="@url" class="imglink">
          <img src="@imagesrc" alt="@title" class="img-responsive full-width"/>
      </a>
     } else {
        <img src="@imagesrc" alt="@title" class="img-responsive full-width"/>
     }
  </figure>

}

I could write the answer with abit more eloquent coding aswell, but to keep it easy to understand I think the format is ok.

Basicly i just want to check wether this loop is empty or not: 

i.GetLoop("ItemPublisher:Item.ProjectImages")

Then make the if else statement.

Does this make sense?

That worked! Thanks. It was much simpler than i thought. Here is the code i got now. Thanks Claus and Mario.

@inherits Dynamicweb.Rendering.RazorTemplateBase<Dynamicweb.Rendering.RazorTemplateModel<Dynamicweb.Rendering.Template>>

@foreach (var i in (GetLoop("ItemPublisher:Items.List"))){

  string title = i.GetString("ItemPublisher:Item.Title");
  string description = i.GetString("ItemPublisher:Item.Description");
  string link = i.GetString("ItemPublisher:Item.Link");
  string url = i.GetString("ItemPublisher:Item.Url");
  string backgroundcolor = i.GetString("ItemPublisher:Item.ImageBackgroundColor");
  string image = i.GetString("ItemPublisher:Item.Image");

  string tagclasses = i.GetString("ItemPublisher:Item.Tags.TagName");
  tagclasses = tagclasses.Replace(",", " ");

  string imgwidth = "624";
  string imgheight = "351";
  
  bool hasimages = i.GetLoop("ItemPublisher:Item.ProjectImages").Any();

  if(hasimages){
  <figure class="col-3-12 col-small-6-12 no-p no-m hover @tagclasses">
    <a href="@url" class="imglink">
        <img src="/Admin/Public/GetImage.ashx?Image=@image&amp;Width=@imgwidth&amp;Height=@imgheight&amp;Background=@backgroundcolor&amp;Crop=0" alt="@title" class="img-responsive full-width"/>
    </a>
  </figure>

  } else {

  <figure class="col-3-12 col-small-6-12 no-p no-m hover @tagclasses">
    <img src="/Admin/Public/GetImage.ashx?Image=@image&amp;Width=@imgwidth&amp;Height=@imgheight&amp;Background=@backgroundcolor&amp;Crop=0" alt="@title" class="img-responsive full-width"/>
  </figure>

  }

}

I see - I thought that a projectImage could esist without a value in File due to your first foreach loop :)

As a note I would recommend that you move the if sentence inside the <figure> so you only need that part of the code once - it's simple matter of as little redundency as possible :)
