Link "home" menu button to "index.php" instead of site root

Hello,
I would like to link the "home" menu button in my site (http://www.torremayor.com.mx/ ) to link to "./index.php" instead of linking back to the site root since, in the site root, I have an index.html page that loads a series of photos, and I would like the users to go back to the HOME page of the webpage, instead of the photo gallery, which they should see only once.
Where can I configure this? and how?
Thanks in advance.

Hi,
probably there are few method to do this.
I can present you two of them.

(1) Don't use index.html, instead use simple Joomla template and article where you'll put your all code from "index.html" then you will have to hide showing first menu item in Menu Manger.
OR
(2) Create two menu, one with only start/default menu item and second with all others, and show only the second one.


That's the theory

Hi, thanks for your quick answer, but those to are not options:
1) It won't work since it is a html using javascript and jquery options and I've tried but it simply won't load, so I decided to execute it outside joomla
2) It won't work (just tried) since I can't make a menu button with "external URL" as type the default menu option.

Do you know where in the code the "base_URL" is hardcoded?

Thanks again.
