Image with EXIF tag plugin

I've modified Image tag plugin into Image with EXIF tag plugin based on the idea of mattn-san's comment . (Thanks, mattn-san!)

If you write text like this:

{% raw %}{% img_with_exif /images/2012/03/first_shot_orion.jpg %}{% endraw %}

You will see the converted result like this:

{% img_with_exif /images/2012/03/first_shot_orion.jpg %}

The title and alt attribute have EXIF data of thie image file.
