<a href="?acao=Alterar&id= <?php echo $coluna[id_categoria] ;?>"><img src="imagens/b_edit.gif" width="16" height="16" border = "0"/></a>

O que todos estão querendo dizer é ... vocão tem o comando de atualizar em seu código ....

Ele não atualiza só porque você clica em um link/botão você deve colocar essa ação exemplo ...

<?php
if (isset($_GET["acao"] == "Alterar") {
 // Conecat no Banco (essa parte você já sabe)

 // Atualiza ao Clicar link com os dados do Link
 mysql_query("UPDATE tabela SET campo='" . $_GET["novoValor"] . "' WHERE id=" . $_GET["id"]);
 echo "Atualizado com Sucesso!!!";
}
?>

<a href="?acao=Alterar&id=1&novoValor=Teste">[ALTERAR]</a>
