Adam,
 I use CuteEditor.EditorSetting when I want to add image to database. So when I click "image Gallery" in toolbar of CuteEdite. it will call class SqlFileStorage . This class use CuteEditor.EditorSetting. you can see my code vb.net below

*******************************
'//<main page>'
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
.
.

 With edStory
                .Setting("CuteEditorFileStorageType") = GetType(SqlFileStorage).AssemblyQualifiedName
                .Setting("DownFile") = ResolveUrl("~/common/viewfile.aspx")
                .Setting("ConnectionString") = getWebConfig("SQLConnectionString")
                .Setting("MailID") = hdnMailIdNews.Value
                .SetSecurityGalleryPath("/")
            End With
End Sub

-------------------------------------------------------------
'//<class SqlFileStorage>
Public Class SqlFileStorage
    Inherits CuteEditor.Impl.FileStorage

    Public Shared ConnectionString As String = ""
    Private c As HttpContext
    Private conn As SqlConnection
    Private setting As CuteEditor.EditorSetting
    Private downfile As String

    Public Sub New(ByVal context As HttpContext)
        MyBase.New(context)
        c = context
        setting = CuteEditor.EditorSetting.GetFromContext(c, True)

        downfile = setting("DownFile")
        conn = New SqlConnection
    End Sub
