It maybe that you have a mod that is conflicting with your attachments. Try globally disabling your mods and then take a look again and see if the attachment images show as thumbs properly. Make sure that you have "View Attached Images Inline" set to "Yes, display thumbnails" and "Thumbnail Creation" set to "Yes" as well. Then you will need a HTML editor like Dreamweaver or use NotePad. DO NOT use MS Word or Word Pad. Global disable: open your includes>config.php file and find:

<?php

and under place:

define('DISABLE_HOOKS', true);

Save and upload again to your server in the includes directory.

If you find that it works after disabling the plugins globally then re-enable the plugins by putting // in front of the code so it looks like this:

//define('DISABLE_HOOKS', true);

Save and upload again.

Then you will have to go through your mods one by one until you find the one that is causing the conflict.

If that does not solve the problem try viewing your site in the default skin. If you still have the problem create a new skin and try viewing the site in it.
