Adding image styles path in page.tpl
Heres an example using theme_image_style() 

$mypath = (file_load(theme_get_setting('heroImage'))-&gt;uri);
print theme_image_style(
  array(
    'style_name' =&gt; 'heroimage',
    'path' =&gt; $mypath,
    'attributes' =&gt; array(
    'class' =&gt; 'YOUR_IMAGE_CLASS'
    ),
    'width' =&gt; NULL,
    'height' =&gt; NULL,
   )
 );
}


I'll be honest, I cant remember why I set height and width to NULL, off the top of my head it helped fix some bug! Hope it helps!
