Background Problem In Opera

[Mr. B]

Let me preface this by saying that I'm not a developer and I'm just learning. I didn't build my site - someone else did and I put it through a validator and found a load of errors (68 to be exact). I'm working on fixing them one by one and I want to learn from you smart people here.

In IE and Firefox, the page in question shows up correctly. I've just started using Opera and it looks awful. For some reason, a background image repeats in places it shouldnt. It should only show up in one area. You can see the page here:

I think the following code has something to do with it, but I'm not sure what:


<tr>
<td><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="50" valign="top" background="http://www.qualitycrashtests.com/images/bg_left.jpg"><img src="http://www.qualitycrashtests.com/images/left.jpg" width="50" height="420"/></td>
<td valign="top" bgcolor="#FFFFFF"><table width="100%" border="0" cellspacing="0" cellpadding="5">
<tr>
<td><img src="http://www.qualitycrashtests.com/images/blog_h.gif" width="388" height="69"/></td>
</tr>

Can anyone help me with this problem? I know there are a lot of problems and I plan to try to fix them all. Any help you can give me with this one would be greatly appreciated. :)
