Display image with ostrio:files?

How do I display a particular image with id using ostrio:files?

From what I can see it doesn’t explain that. I understand that I should use {{imageFile.name}} but what about when I have the id?

UPDATE: I mean when looping through a collection I can use this._id in the helper but can I pass the id in {{fileURL imageFile}} (without setting in the helper with a session or other var)?

Is this issue still persists?
If so, post more of your code here, then can help you.
