More than likely your image links are setup using a hard URL that references your previous .com address.

Try opening your pages in your favorite editor, do a 'Ctrl-F' search for your  previous domain name (example.com) in each page and replace it with your new domain name.

Alternatively, if you think you may move the site again in the future, you could replace the domain name with this wherever it appears:

<?php echo $_SERVER['HTTP_HOST']; ?>

That will output the current domain name wherever the php script runs.
