No, inside the views folder is not good.
Look: You must have 3 basic folders on your project:
system // This is CI framework there are not much reasons to touch this files
application //this is where your logic goes, the files that makes the application,
public // this must be your documentroot
For security reasons its better to keep your framework and the application outside your documentroot,(public_html, htdocs, public, www... etc)
Inside your public folder, you should put your public info, what the browsers can see, its common to find the folders: images, js, css; so your structure will be:
|- system/
|- application/
|---- models/
|---- views/
|---- controllers/
|- public/
|---- images/
|---- js/
|---- css/
|---- index.php
|---- .htaccess
