Firstly, why are you doing this in the first place? If you think that it will make an image appear on your page, you are very mistaken.

Secondly, you are running afoul of the rules regarding mixing headers with content. Once you start sending content you can no longer send headers.

It is sorta covered in the JavaRanch Style Guide.
