Hi Steve

What version of Umbraco are you using? If it's 4.10 or higher then what template mode are you using? Webforms or Razor views? The reason I ask for this is because since v4.10 was released there now is macroscript razor and mvc razor and the way to access the model etc. differs from these two versions :)

Jan,

We are using 4.11.1 and I don't know what the tempate mode is as I don't have access to the install folder.

Luckily we were able to put our heads together and figure it out.

@using umbraco.MacroEngines
@inherits umbraco.MacroEngines.DynamicNodeContext
@{

var mediaFolderId = Model.imageRotatorFolder;

dynamic folder = Library.MediaById(mediaFolderId);

var randomImage = folder.Children.Where("nodeTypeAlias = \"Image\"").Random();
<style type="text/css">
.welcome{
background:url(@randomImage.UmbracoFile) top left no-repeat;
}
</style>
}

And now it's taking into account if someone removes and image, without removing the media altogether.

 @using umbraco.MacroEngines
@inherits umbraco.MacroEngines.DynamicNodeContext

@{  
@* Grab the folder ID *@
var mediaFolderId = Model.imageRotatorFolder;

@* Make the ID Dynamic (for access to media files) *@
dynamic folder = Library.MediaById(mediaFolderId);

@* Grab images that are not null and are in fact "Image" *@
var images = folder.Children.Where("nodeTypeAlias = \"Image\" && umbracoFile != null");

@* Select a random image to display (Will change on every refresh) *@   
var randomImage = images.Random();

    <style type="text/css">
        .welcome{
            background:url(@randomImage.UmbracoFile) top left no-repeat;
        }
    </style>
}

is working on a reply...
