editing navbar button

[محروم.كوم]

am trying to add an RSS feed icon as a button to the navbar
I placed the following code:
Quote:
logouthash=$bbuserinfo[logouthash]" onclick="return log_out('$vbphrase[sure_you_want_to_log_out]')">$vbphrase[log_out]

<img src ="FEED-ICON-IMAGE" />



Now the feed icon and the link is showing but the problem is that the button is always surrounded by a white rim even when I matched the icon bg color with the navbar color "#738FBF"
Have a look at the attached screenshot and please help</div>
