Thank you very much!
If all you want is to put something in a box, you could use the
This package has the advantage that it breaks across pages and fancy stuff like that. Also, changing the padding and margins is easier than with the

But if you insist on importing the existing image, then use the
The following code assumes that your image has been framed.
If your image has not been framed yet, then you need
