Attachement Post

Note: the attachment post type is not available in this list.
I noted this remark, when I was investigating this plugin.
I am very interested in your plugin and specially searching for images ( attachment posts)
Is this always true , I checked with about 5 different themes , but this remark remains the same.

If my investigation is positive I intend to buy the Pro version.
Please clarify this Note.
