The next release of BBM will support photo sharing in multi person
chats. This comes as an addition to existing sharing options that exist
in multi person chats – sending voice notes, sharing your location
powered by Glympse, and sending files from your Dropbox account. We
also understand that customers want to be able to send larger files
through BBM. While our file size limit on shared files has historically
been set at 6MB, we’re increasing this to 16MB in the next release of
BBM. What this means is that you’ll be able to send bigger pictures,
larger documents and longer videos.
