Abstract：
In this paper we discuss the conformal transformations between the Witten’s string field interacting picture and other pictures. Two different interacting pictures of strings and explicit forms of their vertex operators are given. One of them cannot relate to Witten’s picture by a real conformal transformation of parameter a but the other is possible.
