If you encounter with this type of warning message:

Warning: getimagesize() [function.getimagesize]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in ../goodstore/templates/header/header-small-center.php on line 23
Warning: getimagesize(../wp-content/uploads/..../../Logo-GoodStore311.png) [function.getimagesize]: failed to open stream: no suitable wrapper could be found in ../goodstore/templates/header/header-small-center.php on line 23

Please go to appearance->theme options->header settings and change the default logo 🙂

 
Or change allow_url_fopen=0 to allow_url_fopen=1 in your php.ini
