Missing annotations in images outside of galleries

Sometimes in paragraphs you would see this:

```
[[File:Cmglee Thaxted almshouses windmill.jpg|thumb|Almshouses at the parish church of St John in [[Thaxted]].]]
```

Where last part `Almshouses at the parish church of St John in [[Thaxted]]` contains valid annotations. We're currently adding those with `start=0, end=0`.
