yes you are right, because using the same background color in photoshop as on the template (Web color name #xxxxxx) gives unfortunately not the same color in the browsers. I tried this but you then everytime see the corners of the picture. So I'm definetely no graphic person, if i wanna have a special result a try how to get these best with my poor graphic knowledges. I'm pretty shure there are a lot of better solutions

. Maybe you can give me a hint.

Edit:I replaced the gif with an jpg wich has an background. So now it should look better.
