    Random image from gallery

    I am currently pulling the first image from a gallery folder using

    Media gallery = new Media(media_id);
    dynamic pic = gallery.Children.First();

    How could I do something like this

    dynamic pic = gallery.Children.Random();

    If you get the image gallery folder, you can get a random image with ImageGen.

    page 16 in the Documentation PDF.

    Nice.  Now, how do I get the folder? I'd assume something like

    string str_folder = gallery.getProperty("Url").Value.ToString();

    or

    string str_folder = Model.NodeById(gallery_id).Url;

    Neither of which is right

    Hey Tony

    Well that depends on your solution, and how you created your gallery.

    I just assumed, that since you wrote "from a gallery folder using" you already had the path for your gallery.

    Are you using some sort of gallery package ?

    Sorr, my bad.  Read that as "from a media folder".  The only package being used is

    umbraco.cms.businesslogic.media

    In Umbraco 4.7.1 you can easily get a random image from a folder in the media library. Assuming you have the id of your folder:

    dynamic folder = Library.MediaById(1054);
var randomImage = folder.Children.Where("nodeTypeAlias = \"Image\"").Random();
    In my example 1054 is the id of the folder containing the images. The where part is only needed if your folder can potentially contain non-image files.
