modify html

I installed joomla 1.7.1 template with hot photo portfolio of payment and wanted to know how to modify the HTML code for the template. In this template, joomla 1.5. I have not had this problem because when I access the template manager and select the template hot photo, shown above right to see a button with html. That could change the code. Now with joomla 1.7.1 does not appear that link.
My question is how I can access the code?

Thanks and I hope to answer.

Hi, now when you go to template manager you will see two tabs , first is "template styles" and that is not right one, go to second, then click on your template , then click on "edit main template file" . Or just install xExplorer .

Thanx

I have another problem.
In the template I see the gradient from the top, I think the file is called bg_gradient.png

How I can enable this option?

can you please describe your problem in some other words?

yes
my problem is that the design of the demo page of your site hoto photo appears a gradient from the top of the page, and another installation I did in joomla 1.5 also appears, but now in joomla 1.7, does not appear .

Gradient is an effect that has the web design on top.

Ok, that is background image:

templates/hot_photoportfolio/images/bg_gradient.png

css definition is in template_css.php:

#header_wrap {
height:154px;
<?php if($bgStyle<5) { ?>background:url(../images/bg_gradient.png) repeat-x;<?php } ?>
}


So it will not appear on style 5 or 6 by default if you use them, (you can of course just change that number to 7)

also maybe you url is the problem , if yes try putting absolute url.
<your site base>/templates/hot_photoportfolio/images/bg_gradient.png
