could anyone direct me to a good rollover button tutorial for Photoshop or if i could just have the code for it,

basically what i want to do is have a image that is "uploads/click%20here.png" rollover to "uploads/nbrt.png" and have it link to http://mail.google.com/hosted/cgz09.com/

does anyone know how to do this?

Thanks!

do u just mean when you hover over it, the button changes to a hover state? if so then this is simple. this is thru css

a.button{
	background-image: url(files/images/button.gif);
}
a.button:hover{ 
	background-image: url(files/images/button_hover.gif);
}

theres the code, now just make the button you want for normal mode, then add whatever special effects you want for hover mode such as a grey out or changes colors. this is for a link so just do

<a href="http://mail.google.com/hosted/cgz09.com/" class="button">text</a>
