I copied the browser.tpl.php from module to my own theme folder and modified a little bit but the template didn't recgonized. I have cleared all cache.

Per this bug #342350: Override template files based on template filename as well as hook name, so it should be
browser.tpl.php -> imagebrowser-browser.tpl.php
insert.tpl.php -> imagebrowser-insert.tpl.php

the template name included in the imagebrowser module should be changed to avoid this issue.
