ich hatte auch schon so eine Anforderung und hatte damals folgenden Code im Netz gefunden:
Function ExportPictures(doc As NotesDocument, path As String) As Variant
' ==================================================================
' Exports GIF and JPG images from a notes document into given destinationPath
' Picture's filename is path\<docid>_<number>.<extension>
' Tempfile used is path\Base64.tmp which is deleted after export
' Returns a list of strings containing filenames of exported pictures (if any)
' Base64 conversion is performed with Notes internal MIME functions, therefore
' a tempdoc is created but not saved
