If I understand correctly, then Chris is right, and you don't need the
Content-Disposition header, /at all/. Try commenting out the line entirely.
Yeah, you often need it, but as an inline image, you don't.

That said, I can't fathom how it should give you double hits. I just ran this
code:

<?php
$fd = fopen($_SERVER['DOCUMENT_ROOT'] . '/hitcounts.txt','a+');
fwrite( $fd, date('r') . ' | ' . $_SERVER['HTTP_USER_AGENT'] . "\n" );

header('Content-Type: image/gif');
header('Content-Disposition: inline; filename=count.gif');
readfile ($_SERVER['DOCUMENT_ROOT'] . '/images/and.gif');
?>

and it works fine; single hits every time.

BUT.....

I have a Firefox plugin that lets me peek at the response headers, and when I
turned that on -- surprise! -- it *also* requests my script, and thus,
generates another hit. Check all you plugins, especially web development-type
ones that might be generating more requests w/o your knowing it...
