Seleccionar imagen

Dim arxius As String
Dim MiPath As String
'con esto puedes seleccionar los archivos a selecionar
arxius = "Todas las imágenes" & Chr$(0) & "*.jpg;*.jpeg;*.bmp"
MiPath = DialogoComun(Me, " ", arxius, trayprog)
If MiPath <> "" Then
' en mipath tienes la trayectoria + el archivo selecionado
End If
Ahora te mano un modulo que debes colocar en modulos que es el que tiene definida la funcion dialogocomun utilizada en la rutina anterior mas otra que te sirve para seleccionar directorios, browsefolder
