    identifying media image type

    i have a basic image carousel that is looping through images in a folder (within media) , however now that sub folders are added the carousel breaks and i think its bwecause the folders are seen as children of the folder and being treated as images (so cant resolve url)

    how do i check for an image type (to stop folders being rendered)?

    @foreach (var mediaItem in myMediaFolder.Children)              

                {

                    <li style="margin-right:10px;"><img src="@mediaItem.Url" alt="@mediaItem.Name" width="100" height="70"></li>

                }

    Hi Mark,

    you can exlude the folders with an where-statement like this :
     

    foreach (var mediaItem in myMediaFolder.Children.Where("NodeTypeAlias==\"Folder\""))
    {
    ....
    } 


    Or you can check the NodeTypeAlias with an if-statement in the foreach-loop.

    @Soren, I think Mark needs that in reverse :-)

    Either:

    foreach (var mediaItem in myMediaFolder.Children.Where("NodeTypeAlias!=\"Folder\""))
{
....
}

    Or

    foreach (var mediaItem in myMediaFolder.Children.Where("NodeTypeAlias==\"Image\""))
{
....
}
