If you are willing to limit the uploaded picture size to less than 1 meg
you can use the Blob data type. E.g., in your persistent class you'd
have something like
@Persistent
private Blob content;

No, there shouldn't be a difference. Blobs aren't indexed, and neither are
Blobstores. Blobs obviously have the size limit issue and are a bit more
flexible than Blobstores in terms of how you access and manipulate them, but
otherwise, they're using the same mechanisms at a very low level to persist
data.

Hi,
This link says http://code.google.com/appengine/docs/java/blobstore/ that
blobstore requires billing enabled, means blobstore is not freely
available...Google app engine can not allow write to filesystem.Do we have
any other option.
Thoughts ?
