If you want them lined up you'll need to use the following codes:
Code:
<center><a href="url.to.adopt"><img src="url.to.image" border="0" alt="Adopt Me" title="Adopt Me" /></a> <a href="url.to.adopt"><img src="url.to.image" border="0" alt="Adopt Me" title="Adopt Me" /></a> <a href="url.to.adopt"><img src="url.to.image" border="0" alt="Adopt Me" title="Adopt Me" /></a><br />
<a href="url.to.adopt"><img src="url.to.image" border="0" alt="Adopt Me" title="Adopt Me" /></a> <a href="url.to.adopt"><img src="url.to.image" border="0" alt="Adopt Me" title="Adopt Me" /></a> <a href="url.to.adopt"><img src="url.to.image" border="0" alt="Adopt Me" title="Adopt Me" /></a></center>
You could use the <table> tag instead,
Magitek Designs has a decent tutorial there. Otherwise
tutorialtastic.co.uk is a good resource. I lost my favorite though, she hasn't renewed the domain and there haven't been any other updates.
