In order to test websites it is recommended creating a special subdirectory on the shared host (e.g. "test/") into which the test sites are transferred.

Then the test websites can be reached over "www.YourDomainname.com/test" and can be tested and transferred to the website with all images in the root directory "/" of the shared host-account later.

To save the test directory, you can additionally create a .htaccess file for directory protection which is requesting username and password when calling up the subdirectory.
