File/Image entity type not supprt on email

Hi,

I have need to send a image via email chanel and display back the same image in the reply mail from the bot. i am trying it on public sandbox.

I am getting reply email "
I’m sorry, I am unable to find the file. Check the spelling of the file name, and verify that the file location is correct. If you are trying to open the file from your list of most recently used files on the File menu, make sure that the file has not been renamed, moved, or deleted." from the bot.

how to get this work? any help?

Thx.
