Previously, if you tried to attach a file from the Gallery using K9 Mail, the Gallery would be blank.
The newest version, 2.705, has a workaround to allow you to browse the gallery and attach photos and videos directly (Menu>More>Add Attachment (Image or Video)).
This is not the 2.600 version currently in the market, but you can download the 2.705 version here.... Downloads - k9mail - Project Hosting on Google Code
Some discussion on the issue is available here. http://code.google.com/p/k9mail/issues/detail?id=1186#c34
