CSS no javascript

Bom, meu site possui um menu javascript que aparece ao passar o mouse sobre uma imagem. O problema é que essas imagens possuem z-index 3, fazendo com que o menu fique no fundo. Preciso de ajuda para fazer o menu aparecer sobre a imagem.

/applications/core/interface/imageproxy/imageproxy.php?img=http://i50.tinypic.com/i2j6n4.png&key=a91eb0c1d9f9a8d4e5208920ff694ba843a3ff2a66cc6f8440171430bafffc56" alt="Imagem Postada" />

eis o javascript do menu:

Explicando o javascript deste menu:

se você passar o mouse sobre uma área que possua uma div com os segunites atributos: title="header=[nome do item] body=[descrição no menu]", aparece um menu.

Agora olhem o html da minha página, resumido:

#magia1 {
 position: absolute;
 top: 89px;
 left: 50px;
 z-index: 3;
}

<div title="header=[nome do item] body=[descrição no menu]"><img src="imagem.gif" id="magia1" border=\"0\"/></div>

Acho que pra jogar o menu pra frente tenho que colocar um z-index 4 nele, mas n consegui fazer =/
