I'm trying to ignore the file `img/test.jpg` from being followed by SVN. Prompted by [this question](https://stackoverflow.com/questions/86049/how-do-i-ignore-files-in-subversion) I have tried the command:

```
svn propset svn:ignore "img/test.jpg" .

```

Instead of ignoring `img/test.jpg`, SVN tells me `property 'svn:ignore' set on '.'`.

Also, when I do `svn status` I now get the extra line:

```
 M      .

```

How can have SVN ignore a file?
