Google does not index the dummy index.html
If you look at my website http://www.google.ch/search?hl=d...gle-Suche&
you will see that Google overrides the dummy index.html file and Google indexes the first real page instead.
On your website there's no content on Google since your first page doesn't contain any text. It's all images. Maybe you wrote text behind the images but that text gets turned into image as well (Read Note 3 on my Google FAQ).
You really should rebuild your first page and add some text to it.
