Enable capture of image recognition metadata

[kitenetter]

Jim tells me that image recognition metadata is being captured within the apps for EBMS and e-surveyor, but not within the iRecord app. We would like to capture this data from the iRecord app as well.

I'm hoping that it will be relatively straightforward to apply the process from the other apps that are already doing this. Can you let me know how big a job this is?

@kitenetter It's a small task, I can do this as part of #237.
