Resizing avatars in postbit?

[shibby2]

Hey guys, I'm making a mobile skin and would like to display the poster's avatar next to their name in postbit_legacy. I added the bit of code to do this, but since it's a mobile skin, the avatars are way too big.

How would I go about to make them smaller, just for that skin? Don't know exactly what size I would want just yet, guess it will take some testing, but they have to definitely be smaller.

Any help would be awesome, thanks!

I actually figured it out.. somewhat. This is my code:

<if condition="$show['avatar']">
				
					&nbsp;<br /><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl] width="40px" height="40px" <phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a>
				
			</if>

Only thing is, some of the avatars come out as rectangles (tall and thin). Is there a way to make them perfectly square instead of rectangle?
