Creates the createImage method for the ImagePage class The method: * has two parameters:   1. access_rights(defaults to nil): used to defined which radio button to check under access controls   2. embargo_date(defaults to nil): allows tests to not include an embargo date to test preventative measures against a blank embargo date field * generically fills in the necessary information to create the file * uses access_rights to choose the desired access control rights (if nil then defaults to open) * checks contributor agreement * then creates the image work
