Private Sub Command1_Click()
'use common dialog control to allow user the select an image file
    With Dlgs
        .Filter = "(*.bmp;*.jpg;*.gif;*.dat;*.pcx)| " & _
            "*.bmp;*.jpg;*.gif;*.dat;*.pcx|(*.psd)|*.psd|(*.All " & _
            "files)|*.*"
        .ShowOpen

        If .FileName = "" Then Exit Sub

        FN = .FileTitle
        'Open File And Read as Binary (open the file selected by user)
        Open .FileName For Binary Access Read As #1

'create buffer in memory to hold the contents of the file
        FileBinary = Space(LOF(1))

'read the file into the buffer created and close the file
        Get #1, , FileBinary
        Close #1


        'Add File To DB
        rs.AddNew 'tell ado recordset object that you are adding a new record
        rs!Img_name = FN 'set a text field to the file name of the file selected by user
        rs!Image = FileBinary 'set a memo field with the contents of the buffer
        rs.Update 'tell the ado recordset that you want to save the new record

        'Refill List
        GetAllFiles 'unknown proceedure
    End With
End Sub

as for the second piece of code on that page...
query the database, check to see if record found, no>notify user, else>check to see if file exists and delete it if necessary, then save the contents of the memo field to the hard drive and use the load picture function to display the picture into an image control...

Good Luck

Well the code provided on that page is DAO and not ADO. So you need to have a reference to DAO. Also, if that little snippit you gave is representive of your actual code, you should be getting an error because of the comma and blank thereafter (Compile Error: Expected Expression)

Good Luck
