Guardar Imagen en SQL

[jafera]

Yo lo hago así:

Código Delphi [-]
procedure TF_Material.DBEdit1Change(Sender: TObject);
var
        jpg:TJpegImage;
        foto:TMemoryStream;
begin
        PageControl1.ActivePage := TabSheet1;

        If SysUtils.FileExists('C:\Trens_1.0\Temp\Temporal.jpg') then
        SysUtils.DeleteFile ('C:\Trens_1.0\Temp\Temporal.jpg');

        If F_Moduldades.MaterialFoto.AsString <>'' then
        begin
                Jpg:=TJpegImage.create;
                Foto:=TMemoryStream.create;
                try
                        F_Moduldades.MaterialFoto.SaveToStream(Foto);
                        Foto.Seek(0,soFromBeginning);
                        Jpg.LoadFromStream(Foto);
                        Jpg.SaveToFile('C:\Trens_1.0\Temp\Temporal.jpg');
                        Image1.Picture.Assign(Jpg);
                finally
                        Foto.Free;
                        Jpg.Free;
                end;
        end
        else
                Image1.Picture.Assign(nil);
end;
