Setting the filter to an OpenFileDialog to allow the typical image formats?

Question

I have this code, how can I allow it to accept all typical image formats? PNG, JPEG, JPG, GIF?

Here\'s what I have so far:

public void EncryptFile()

In order to match a list of different categories of file, you can use the filter like this:

        var dlg = new Microsoft.Win32.OpenFileDialog()
        {
            DefaultExt = ".xlsx",
            Filter = "Excel Files (*.xls, *.xlsx)|*.xls;*.xlsx|CSV Files (*.csv)|*.csv"
        };
