Gallery & Mambo - too much whitespace around it

Hi, I've created a website in Mambo and used gallery as the tool for showing my pictures. Installing was no problem, it works fine, also technically...

However, if you look at an entire picture (not the thumbnails), there is a lot of useless whitespace above it. I think it is about 40-50 pixels...

Click to see it yourself: Example

Is there any chance or possibility to delete this whitespace at the top and move my pictures a bit up? It can be the difference between normaal viewing and having to scroll down everytime to see the whole picture..

Thanks for your help,

Michael
