Header footer how to

Just paste the code below into your custom box and replace the things in bold with what is required:

<img src="HEADER IMAGE URL"><div class="gr-body"><div class="gr"><div align="center" class="pp">BOX CONTENT</div></div></div><img src="FOOTER IMAGE URL">


NOTES:
The header and footer should be 386 pixels wide for the standard size...
Using more than one in one custom box may muck up... not sure why as im quite a newbie to all this code stuff...
