Is the plugin is compatible with WPML ?
Thank you, works like a charm. Much appreciated!
No, you shouldn't pay. Just get your copy for free and make experiments with it. If you don't like what happens - just remove it and that's it. No need to pay or cancel something.

It's simple to do with this addon
It contains some code to limit post_type to 'attachment' only:
Pretty simple. If you want to set up your own post_types, just modify this code. You can read about full WP_Query() parameters at the Wordpress official documentation.
Should be you are using the "WPFTS :: Live Search" widget. This widget is intended to show this live search data. If you don't want them, simply use the native WP Search widget.
Hope it helps.
