Pictures does not appear on WordPress web site after manual transfer from another server.
Preferable way of transferring the WP application is to use Plesk Migration Manager to transfer from the supported platform. But in case if WP site should be transfered from the unsupported platform, you may refer to these instructions.
There are few steps you need to follow to perform the WordPress website transferring:
- Backup website files on old server and transfer them to new one;
- Create website database dump using GUI (like phpMyAdmin) or using the shell;
- Make sure database does not contain old home path from previous hosting;
- Restore database to new server.
