NextGen Slideshow

Hello everybody

I’m pretty new here on this forum. I’m trying to set up a wordpress website (non-blogging). Everything is working fine (I have php knowledge ect) but I have a few problems with the NextGen slideshow plugin.
I already installed the plugin and everything is working fine when I use the shortcode
[nggallery id=1 template="sliderview"]
The slideshow have to appear on each page of my website. When I use the shortcode, i don’t have enough freedom with the css, placement of the slideshow ect.
So I used Google for some solutions. One of them was the use of the following code.
<?php echo do_shortcode('[slideshow id=1 w=600 h=250]'); ?>
I’ve put this part of code into my header file because I want to show the slideshow on each page, so not in a specific page or post.
The code is working and the slideshow is in my header but i do not have any layout.
I just have the photo (I’m missing the white box around the picture, the pagination, …)
Can somebody help me because i do not have any idea ’bout what i’m doing wrong.

Thanks
