Change Event when Image modified

Hi all.
Just wondered if there was an event available which I can listen for to tell me if an image has changed (either picked from the gallery, or a photo taken, or annotated etc). Can't see anything obvious in the documentation.
Apologies if I've missed something.
Cheers for now.
Marcus.

HI Marcus,
The Image element will only post the image data to the server if there is any change (e.g. the user took a photo, or picked a photo from the gallery).
So you can tell if the image has changed by checking (in your RDML program) if the Image property is present (or Annotation.Image property for separate annotation image).

Hi Tony.
Ah okay thank you for that info... but what if I'm OFFLINE and need to monitor for a change and run some JavaScript?
I guess I can check for a difference in blob size... but I need to do that in an event fired when I return from the taking / picking the image.
Is there an event available?
Cheers!
Marcus

Unfortunately there is no such event.
We can add it if it's required, let us know.
