Presentation Page before index.php

[eluser]ferex[/eluser]
Hi

is there a way to make a presentation page

like to have

presentation.php
index.php
...


so when I access the site it first goes to presentation
to choose the desired language accompanied with a nice logo image
and then, after a language has been chosen
the index page comes in


Another question please

Is there a way to while looking at this presentation page
the index is being loaded? to save time.


Thank you for reading.
