Offline Photo & File Transfer Through Openfire

I am using the latest version of Conversations along with Openfire 4.5.1
The server stores & forwards text messages for offline users
But it does not do it for photos/files.
I am only able to send photos & files only when receiver is online.
Receiver is able to download only when sender is online.
Setting up my own server for the first time!
Please help!!

There are many different ways to send binary data using Openfire. You appear to be using a one-on-one transfer. Consider using the HTTP File Upload plugin (which implements XEP-0363). This will store the binary data on the server, which, in theory, should make it possible for the intended recipient to download it later.
