Okay, how do I put a banner at the top of the comic instead of the comic's name in white?

In the Html template, replace:

<!--Comic Title Area-->
<table align="center" border="0" cellpadding="0" cellspacing="0" width="600">
<tr>
<td><div align="center"><font style="font-size:48px;color:black;"><b>hero tales</b></font></div></td>
</tr>
</table>


with:

<!--Comic Title Area-->
<table align="center" border="0" cellpadding="0" cellspacing="0" width="600">
<tr>
<td><div align="center"><img src="LOCATION OF THE BANNER"></div></td>
</tr>
</table>
