Plugin to check for members avatar in footer

[glennybee]

Hi folks,

I'm coding a side column in the footer template and I want to show the members avatar at the top. I can't use the code from the postbit templates because they don't parse in the footer.

I can use this to show the avatar (avatars are stored in the filesystem):

<div align="center">
<a href="member.php?$session[sessionurl]u=$bbuserinfo[userid]"><img src="customavatars/avatar$bbuserinfo[userid]_$bbuserinfo[avatarrevision].gif" alt="$bbuserinfo[username]'s Avatar" /></a>
</div>

But if a member doesn't use an avatar you get the red cross and it looks crap.

So I need a conditional to check for an avatar before trying to show it. The following don't work:

<if condition="$show['avatar']">
<if condition="$avatarurl">
<if condition="$bbuserinfo['avatar']">

So I'm guessing I need to create a plugin to check for this.

Can anyone help please?

Thanks!
