If you click "Import Listings" and listings are loaded without images it is probably because of your server settings. To fix it please:
1. Visit root folder of your WordPress
2. Backup wp-config.php file
3. Edit wp-config.php file
4. Add this line:
define('ALLOW_UNFILTERED_UPLOADS', true);
above "That's all" message so it will look like this:
define('ALLOW_UNFILTERED_UPLOADS', true);
/* That's all, stop editing! Happy blogging. */
5. Please move all properties that was downloaded incorrectly to the trash (check > move to trash > apply)
6. Remove from trash (trash > empty trash)
7. Please click "Import Listings" button again
