Maybe I should mention that I need to have the img path in this foreach loop:

@{
   var newsAreaNode = Model.SideNormals.First();
}
@{
foreach (var item in newsAreaNode.Descendants().Where("NodetypeAlias == \"Artikel\""))
{
@*imgpath here*@
}
}

Hi Robin

I have had my struggle with the multi-node tree picker too. I needed it for content nodes. Here is my code, modified based on your inputs... (this code is for the multi-node tree picker's data saved as csv (not xml)) 

@{
 string[] imagesString = Model.MiltiNodeTreePickerPropertyTypeAliasHere.Split(',');
 List images = new List();
}
@foreach(string i in imagesString)
{
 if (!images.Contains(i))
 {
  images.Add(i);
 }
}
@foreach(var item in images)
{
 var image = Library.MediaById(item);
 <img src="@image.umbracoFile" alt="@image.Name"/>
} 

PS: Not tested...

Thank you Kasper - this looks promissing, however the img path NEEDs to be in this foreach loop:

foreach (var item in newsAreaNode.Descendants().Where("NodetypeAlias == \"Artikel\""))
{

@*imgpath here*@

}

Can I squize your example with all loops inside that...?

I think I need more information about your structure to help more. But the @image.umbracoFile is the image's path. 

Thats fair enough - I've a standard Umbraco Rss page (Customized to read only certain doc types) - by which I reads some info from - in that case I need to read an image path:

@{

//Change mime type
umbraco.library.ChangeContentType("text/xml");   

//Get the domain 
var siteURL = "http://" + Request.Url.Host;

//Get the news area node (only one of these per site)
var newsAreaNode = Model.SideNormals.First();

//Get the latest createDate of all news items to use as the RSS feed updateDate
var RSSFeedPubDate = newsAreaNode.Children.Where("articleDate <= DateTime.Now && Visible && umbracoNaviHide != true").OrderBy("UpdateDate desc").First();

}

Okay. I think you may need to hardcode the root, then you can add the image path. Here is some new code:

@{
 var root = "http://www.domain.com";
 foreach (var item in newsAreaNode.Descendants().Where("NodetypeAlias == \"Artikel\""))
 {
  if(item.HasValue("MiltiNodeTreePickerPropertyTypeAliasHere"))
  {
   string[] imagesString = item.MiltiNodeTreePickerPropertyTypeAliasHere.Split(',');
   List images = new List();
   foreach(string i in imagesString)
   {
    if (!images.Contains(i))
    {
     images.Add(i);
    }
   }
   var image = Library.MediaById(images.First());
   var output = root + image;
  }
  <item>
   <img>@output</img>
   <title>@item.Name</title>
   <link>@item.Url</link>
   <pubDate>@item.UpdateDate.ToString("r")</pubDate>
   <guid>@item.Url</guid>
   <content:encoded><![CDATA[@item.bodyText]]></content:encoded>
  </item>
 }
}

Ha! We added answer at the same time :-)

Good you found a solution.

is working on a reply...
