If you're a subscriber, you can actually make graphics go a little outside your journal for a neat effect. To do this, create a little graphic that you want to include, and leave the topmost 15 pixels empty. If you can, save it as GIF, so the background is actually transparent.

Then, go to your journal and paste these lines at the very bottom of your footer section:
<img src="website address of your first picture" align="left" /><img src="website address of your second picture" align="right" />

That's it - keep in mind that it only works if the visitor uses Firefox, for all other browsers it's displayed inside the journal as usual (so make sure your graphics look good for that case too). If you need some webspace to put your picture, you can give imageshack.us a shot ^-^

(if you need even more details - the topmost 9 pixels will still be inside your journal, and the maximum height you should have is 36 pixels ^-^ The character in the journal is Jackie, by the way ^^)
