Probably the process's working directory is not the directory that contains the image. You can either specify the full path to the image:

system("plot /full/path/to/image.jpg");

or use chdir to change the working directory before running the command:

if(chdir("/full/path/to/") == -1)
    ; // TODO handle error
system("plot image.jpg");
