around this issue In Java, you would instantiate a BlobInfoFactory and use BlobInfoFactory.queryBlobInfos.
Then for each blob, you would run BlobstoreService.serve(...) with the BlobKeys returned from the BlobInfos. You still might end up with broken entity relationships - there's no way to guarantee each blob will end up with the same key it was originally loaded with. You'll have to account for this in your application.

I wish did fix the issue. You can achieve the same without using blobstore api. I think you have to just get the url and get the content using urlfetch().content method and store it as a blob property.
code :
url = "imageurl"
result = urlfetch.fetch(url)
if result.status_code == 200:
   prof.avatar = db.Blob(result.content)

wish helps you
send_blob() doesn't involve your application reading the file from the API, so the 1MB limit doesn't apply. The frontend service that returns the response to the user will read the entire blob and return all of it in the response (it most likely does the reading in chunks, but this is an implementation detail that you don't have to worry about.
