In an image processing apparatus, a processor transmits to the server a first registration request including incapability information. The incapability information indicates that any of a plurality of settings for an image process is incapable of being designated. The processor receives from the server a first function execution instruction including the account information, and first relation information which is related to a fact that no setting for the image process is specified. The processor acquires from a memory setting specification information correlated with the account information. The processor displays a specification screen for prompting a user to specify one setting from among one or more settings for the image process specified by the acquired setting specification information. In a case where the user specifies a first setting via the specification screen, the processor controls an image processing execution unit to execute the image process in accordance with the first setting.
