Javascript pushes header down

[nitro]

I have two short javascripts for SEO tracking in my HTML page. If both are in the page, the content is pushed down 2 lines. If I remove either one, the page looks fine; when I put the other on in, the content has two blank lines above.

Any ideas what this is about?

Thanks!

are the javascripts embedding a little image into the page? that's a common thing for SEO tracking stuff to do.
if you've got images set to display:block in your CSS, or with big margins or something, then that might be why.

if you can't see the image when you view the source code of the page, then try viewing the generated source instead. (you'll have to install the webdeveloper plug-in for firefox to see that, or something similar)
