generate relative path error when upload image url with window system

When upload image url to a contact the system get the wrong image path when running civiCRM with Joomla on window with XAMPP

The error code is at file CRM/Contact/BAO/Contact.php on line 753

$customFileUploadDirectory = strstr( $absolutePath , '/media' );

This code cause the problem. cause in window system the absolute path is "...\media" not "/media"
My solution is replace all the "\" with "/"

$customFileUploadDirectory = strstr( str_replace('\', '/', $absolutePath), '/media' );

and then the upload image url will be work fine.

also I think this bug also occur at line 757 for drupal version and 760 for standalone version

$relativePath = $config->userFrameworkBaseURL . $absolutePathStr;

fix with

$relativePath = $config->userFrameworkBaseURL . str_replace('\', '/', $absolutePathStr);
