1. An image processing apparatus comprising: a processor; and memory storing computer readable instructions, when executed by the processor, causing the image processing apparatus to: acquire plural keywords including a first keyword and a second keyword different from the first keyword; generate template image data representing a template image using the acquired plural keywords, the template image including a body area for writing information therein by a user, and also including a keyword area including plural character images representing the plural keywords, respectively, wherein the keyword area is for writing information therein by the user for specifying a target keyword from among the plural keywords, the target keyword specifying a folder which is for storing a target image data file and is comprised in a storage server, the target image data file representing a target image including the body area having information written therein by the user; provide the generated template image data to a printing unit for printing the template image the body area and the keyword area; after providing the template image data, acquire a transmission file including a first original image data generated by optically reading a first document including the template image and a second original image data generated by optically reading a second document including the template image and being different from the first document, wherein the first document includes a first body area having information written therein by the user and a first keyword area having information written therein by the user for specifying the first keyword as the target keyword from the plural keywords, and the second document includes a second body area having information written therein by the user and a second keyword area having information written therein by the user for specifying the second keyword as the target keyword from the plural keywords; specify the first keyword as the target keyword from the plural keywords by analyzing the first keyword area in the first original image data included in the acquired transmission file; specify the second keyword as the target keyword from the plural keywords by analyzing the second keyword area in the second original image data included in the acquired transmission file; generate a first target image data file representing a first target image including the first body area by using the first original image data included in the acquired transmission file; generate a second target image data file representing a second target image including the second body area by using the second original image data included in the acquired transmission file; after specifying the first keyword as the target keyword, transmit the generated first target image data file to the storage server through a network so as to store the generated first target image data file in a first folder which is comprised in the storage server and specified by the first keyword; and after specifying the second keyword as the target keyword, transmit the generated second target image data file to the storage server through the network so as to store the generated second target image data file in a second folder which is comprised in the storage server and specified by the second keyword.
