Delay After mobilePhotoPickPhoto?

[Scott Rossi]

I have app in which I'm using mobilePickPhoto to pull an image into a
stack from the user's photo library.  Once a (large) photo is chosen it
can take several seconds for the photo to be available on the card.  The
problem is, there's doesn't seem to be any way to display a wait or
progress indicator after a photo is selected from the picker.

My understanding is that the only options for mobilePickPhoto "library"
are to limit the import size.

Has anybody figured out a way to show wait or progress once a photo is
chosen from the photo picker?

Thanks & Regards,
