Hi Keerthi,
Welcome to Adobe Community !!
I am assuming you are using AEM 6.5.7, right?
Have you created an integration between AEM - Scene 7 on your AEM Author?
As per Anish's suggestion, you can use "Scene 7" component or directly search for asset available [1] on your configured Scene 7 / Dynamic Media Classic account and add them to an Image Component.
[1] : AEM - Scene 7 integration needs to be configure for that feature.
Thanks,
Vikram Gaur
