  We study the expectation values of Wilson-loop operators with the
insertionsof local operators Z^J and Zbar^J with large R-charge J from the bulk
viewpoint of AdS/CFT correspondence. Classical solutions of strings attached to
such deformed Wilson loops at the conformal boundary are constructed and are
applied to the computation of Wilson-loop expectation values. We argue that in
order to have such solutions for general insertions at finite positions in the
base spacetime of the gauge theory, it is crucial to interpret the holographic
correspondence in the semi-classical picture as a tunneling phenomenon, as has
been previously established for holographic computations of correlators of BMN
operators. This also requires to use the Euclideanized AdS background and
Euclidean super Yang-Mills theory.
