How about just using the option of uploading your own icon set and allowing to pull form sever in which your site resides? In the wp-wunderground text file, it gives “instructions” how to do this, but it doesn’t make entire sense to me. here is what the text doc says:
If you want to use your own icons, you would add a filter to the bottom of your theme’s functions.php file:
<h3>Version 1.2+</h3>
add_filter('wp_wunderground_forecast_icon', 'use_custom_wunderground_icons');
function use_custom_wunderground_icons($content=null) {
$myIconFolder = 'https://www.example.com/images/';
$myFileType = '.gif';
$content = preg_replace('/http\:\/\/icons\-ecast\.wxug\.com\/i\/c\/[a-z]\/(.*?)\.gif/ism', $myIconFolder.'$1'.$myFileType, $content);
return $content;
}
<h3>Version 1.1</h3>
add_filter('wp_wunderground_forecast', 'use_custom_wunderground_icons');
function use_custom_wunderground_icons($content=null) {
$myIconFolder = 'https://www.example.com/images/';
$myFileType = '.gif';
$content = preg_replace('/http\:\/\/icons\-ecast\.wxug\.com\/i\/c\/[a-z]\/(.*?)\.gif/ism', $myIconFolder.'$1'.$myFileType, $content);
return $content;
}
Can anyone make better sense of this? What do I name the actual icons?
Also, from the Wunderground site, vague reference is given here to adding a set of icons. Click here to view the post.
