Code Suggestion: Alt Image to Logo

This may have already been updated, but I had to hack the theme to add an alt image to the logo. Here is the code I changed:

Change this core code on theme update:

Theme/framework/php/function-set-avia-frontend.php

Line 416 to:

if(!function_exists('avia_logo'))
{
	/**
	 * return the logo of the theme. if a logo was uploaded and set at the backend options panel display it
	 * otherwise display the logo file linked in the css file for the .bg-logo class
	 * @return string the logo + url
	 */
	function avia_logo($use_image = "", $sub = "", $headline_type = "h1")
	{
		$use_image 		= apply_filters('avf_logo', $use_image);
		$headline_type 	= apply_filters('avf_logo_headline', $headline_type);
		$sub 			= apply_filters('avf_logo_subtext',  $sub);
		$alt 			= apply_filters('avf_logo_alt', get_bloginfo('name'));
		$link 			= apply_filters('avf_logo_link', home_url('/'));
		
		if($sub) $sub = "<span class='subtext'>$sub</span>";

		if($logo = avia_get_option('logo'))
		{
			 $logo = "<img src='{$logo}' alt='{$alt}' title='{$alt}'/>";
			 $logo = "<$headline_type class='logo'><a href='".$link."'>".$logo."$sub</a></$headline_type>";
		}
		else
		{
			$logo = get_bloginfo('name');
			if($use_image) $logo = "<img src='{$use_image}' alt='{$alt}' title='{$alt}'/>";
			$logo = "<$headline_type class='logo bg-logo'><a href='".$link."'>".$logo."$sub</a></$headline_type>";
		}

		return $logo;
	}
}

Let me know if this has been fixed so I can remove my hack- thanks!
