looks like finder covered most everything, but 
here's the basics:

the reason you got a funny-sized was because your 
image was too large.  DON'T resize it using the 
IMG tag's height/width attributes.  you're only 
taking a large image and squishing it into a 
smaller space.  it will still load slow as a large 
image will, and will also likely end up distorted 
looking.  you'll need to resize it in a graphic 
editing program, such as Paint Shot Pro.  

most of the code for the table is extraneous.  to 
get the ring to work you only need the guts, which 
is this:

and i've replaced the < and > symbols with [ and 
], because this forum renders html within posts.  
you WILL have to make the switch back if you're 
going to use this code. 

[A HREF="http://www.animanga.com/ring/" 
target=_parent]Link text goes here[/A].

this is the anchor for the webring homepage.  you 
can make the text for the link anything you want, 
or even an image if that floats your boat.

[A HREF="mailto:yourname@youremail.address"]Link 
text goes here[/A]. 

a mailto anchor.  this will automatically pop up 
an addressed mail in the appropriate email client, 
provided the user's client is configured properly 
for the browser they're using.  again, use any 
text for the link you'd like.  

[A HREF="http://www.animanga.com/cgi-bin/ring?
aid=animecels&uid=1&cmd=next" target=_parent]Link 
text goes here[/A]. 

anchor for the next page in the ring.  

[A HREF="http://www.animanga.com/cgi-bin/ring?
aid=animecels&uid=1&cmd=skip" target=_parent]Link

ring homepage.  

you don't need to put the code in a gray table, 
and you don't need to use images at all.  in fact, 
you can get away with leaving off some of these 
links if you really want to.  but the 
next/previous/index links are really the heart of 
a web-ring, and should be included or else 
you'll be responsible for breaking the ring, 
and might get yourself booted from it ~_^
