    Randomly selecting an image from a folder

    Templates, (partial) views and macros
    Umbraco 7

    I have created a folder in Umbraco and I would like to display a random image from that folder on my page.

    I found a solution from a few years ago which was giving me compile errors

    dynamic folder = Library.MediaById(1054);
var randomImage = folder.Children.Where("nodeTypeAlias = \"Image\"").Random();

    I found that I have to add the proper inherits in my file 

     @using umbraco.MacroEngines
 @inherits DynamicNodeContext

    but this it gives me an error because I already have a @model I'm using in the first line

    The 'inherits' keyword is not allowed when a 'model' keyword is used.

    Thanks for any help

    Can you do the following?

    var folder = Umbraco.TypedMedia(1054);
var randomImage = folder.Children().Where(x => x.DocumentTypeAlias == "Image").Random();

    Hi Kilgore,

    The problem is with the header of your view.

    You can't use model and inherits directives.

    Also do not use dynamic types, it will be easier to manage this code after.

    Thanks,

    Alex
