@inherits Umbraco.Web.Macros.PartialViewMacroPage

@*
    Macro to display a series of images from a media folder.

    How it works:
        - Confirm the macro parameter has been passed in with a value
        - Loop through all the media Ids passed in (might be a single item, might be many)
        - Display any individual images, as well as any folders of images

    Macro Parameters To Create, for this macro to work:
    Alias:mediaId     Name:Select folder with images    Type:Single Media Picker
*@

@{ var mediaId = Model.MacroParameters["mediaId"]; }
@if (mediaId != null)
{
    @* Get the media item associated with the id passed in *@
    var media = Umbraco.TypedMedia(mediaId);
    var selection = media.Children<Image>().ToArray();

    if (selection.Length > 0)
    {
        <ul>
            @foreach (var item in selection)
            {
                <li>
                    <img src="@item.Url" alt="@item.Name" />
                </li>
            }
        </ul>
    }
}
