Fix for img sizer plugin

// find the following around line 127 of pi.imgsizer.php

// -------------------------------------
// do fetch remote img and reset the src
// -------------------------------------		
if($remote && $img['url_src']){
	$img['src'] = $this->do_remote($img);
}

// immediately after that, enter the following

if((strrpos($img['src'], "/") == (strlen($img['src'])-1)) || $img['src'] == "."){
   $TMPL->log_item("imgsizer.Error: image source is blank");
   return $TMPL->no_results();
}
