Hi Avdhesh,
No, Blobstore and Datastore are not the same. Blobstore is more like
Amazon S3. You have a key, and a binary blob of data. All you can do
is insert and delete. Blobstore does not have the same restrictions on
the amout of data you can store.
There is one very interesting feature of Blobstore. There is an
additional API, that will do image transformations on the fly. For
example, you can specify the size of image you want, on retrieval. So
there is no need to store thumbnails on all your uploaded images.
Details here:

Hey Stuart
We support deploying PhotArk in Google AppEngine, and we seem to be
a good option for you. We still need to add a small adapter to read
from the blob store, but other then that, we should be able to be your
GAE Gallery. Would you feel comfortable helping us write the "blob
store" adapter ?
Hi Luciano, yes I am happy to help. I have only been working with
Java/Eclipse/AppEngine for a week, so it's fairly new to me. I'm using App
Engine as a data store for a Mono/C# server application I have. I'm working
with pictures at the moment, but would like to add video support later.
