Why my repository name and tags are not coming after building docker image using the docker file?

Question

I am unable to see the name of my docker image (myimage1). It is as followes:-

The docker file I have used is :-

FROM centos:7
MAINTAINER Dev
LABEL remarks = "Test Image"
RUN yum install update && yum install httpd -y && yum install update

I am using the command to build an image:-

docker build -t "myimage1" .

I am expecting image should be myimage1, not <none>
