Componente para envio de mensagens de erro por e-mail

Galera,

Desenvolvi um componente para enviar mensagens de erro por email e gostaria da opinião de vocês e também da ajuda para melhorá-lo:

unit SendException;

procedure CapturaTela;

end;

procedure Register;

implementation

uses dm_SendException;

finally
IdSMTP.Disconnect;
DeleteFile(ArquivoImagem);
