Read values from xml and add them into list

How to read the values (image1, image2, image3) from this xml file. Its a sample and I dont know about the number of values exactly. I mean maybe the xml file has more Image Name . I want to add these images name into a list. and also I want to get ImageInterval value and set it into int variable.

    <Sinage DataBase>

    <Image>
        <ImageName>
            image1
        </ImageName>

        <ImageName>
            image2
        </ImageName>

        <ImageName>
            image3
        </ImageName>

        <ImageInterval>
            4
        </ImageInterval>
    </Image>
</Sinage DataBase>

Its my list:

public List<string> ImageName { get; set; }

I used above code for reading data but display error : Illegal character in path

XDocument doc = XDocument.Load(global::TestGraphic.Properties.Resources.xml);

    var ImageName = doc.Descendants("ImageName");

    foreach (var image in ImageName)
    {
        MessageBox.Show(image.Value);
    }
