"WPMU Theme Select" Plugin Screenshot Path Problem!!!

I am using WPMU Theme Select Plugin with WP 3.0.
The problem is the screenshot path.
The code bellow:
<img style=”margin-left:40px;display:block;” width=”185″ height=”126″ alt=”” src=”‘.WP_CONTENT_URL.$theme[‘Template Dir’].”/”.$theme[‘Screenshot’].'” />

Out-puts:
http://hakdak.com/wp-content/home/username/public_html/wp-content/themes/twenty-ten/screenshot.png

Which I want:
http://hakdak.com/wp-content/themes/twenty-ten/screenshot.png

by deleting: /home/username/public_html/wp-content

I am pasting bellow the full plugin code:
wpmu_theme_select.php

[huge chunk of code moderated – use pastebin.com]

Please help me to overcome the problem!!!
