I suggest you to serve Image from Blobstore as an Image Service, It will give your image better performance, sizes etc.

See my Code Below.

ImagesService services = ImagesServiceFactory.getImagesService();
ServingUrlOptions serve = ServingUrlOptions.Builder.withBlobKey(blobKey);    // Blobkey of the image uploaded to BlobStore.
String url = services.getServingUrl(serve);

You will get the URL for the image which you can easily put in the Image tag of HTML.

<img src="url" />
