Try this:
<div class="sys_ml" style="width:__main_div_width__;">
<div class="sys_ml_wrapper">
<bx_injection:injection_logo_before />
__main_logo__
<bx_injection:injection_logo_after />
</div><img
src="http://www.isuncoast.com/templates/base/images/grass.png"style=margin-bottom:0px;float:right;margin-right:20px;margin-top:-141px"/>
</div>
Note that the image code is now inside the "sys_ml" Divide.
Your image height is 141px so you should set margin-top to -141px as above... so if you alter the height of your graphic then you will also need to alter this to match.
Or for a simpler solution:
<div class="sys_ml" style="width:__main_div_width__;background-image:url('http://www.isuncoast.com/templates/base/images/grass.png');background-repeat:no-repeat;background-position: right;">
<div class="sys_ml_wrapper">
<bx_injection:injection_logo_before />
__main_logo__
<bx_injection:injection_logo_after />
</div>
</div>
Then you will have to edit the css for the Quotes div to move that left.
