arclite theme- changing avatar

I am running the Arclite theme.

I am trying to find a way to change the avatar on the admin profile. I have an image (in both jpg and gif format) that I want to use as the avatar. I think it is pulling my avatar from my wordpress.com account, though I’m honestly not 100% sure. Either way it needs to change.

I am still working on figuring this out. From what I can tell the avatar is in this section of code:

<div class=”profile”>
<div class=”avatar left”><?php echo get_avatar($curauth->user_email, ‘128’, $avatar); ?></div>
<div class=”info”>
<p>
<?php
if($curauth->user_description<>”): echo $curauth->user_description;
else: _e(“This user hasn’t shared any biographical information”,”arclite”);
endif;
?>
</p>
<?php
if(($curauth->user_url<>’http://&#8217;) && ($curauth->user_url<>”)) echo ‘<p class=”im”>’.__(‘Homepage:’,’arclite’).’ user_url.'”>’.$curauth->user_url.’</p>’;
if($curauth->yim<>”) echo ‘<p class=”im”>’.__(‘Yahoo Messenger:’,’arclite’).’ yim.'”>’.$curauth->yim.’</p>’;
if($curauth->jabber<>”) echo ‘<p class=”im”>’.__(‘Jabber/GTalk:’,’arclite’).’ jabber.'”>’.$curauth->jabber.’</p>’;
if($curauth->aim<>”) echo ‘<p class=”im”>’.__(‘AIM:’,’arclite’).’ aim.'”>’.$curauth->aim.’</p>’;
?>
<div class=”clear”></div>
</div>
<div class=”clear”></div>
</div>

but I’m just not sure. Any help would be appreciated.
