I hadn't thought of 'iconifying' an image for this purpose, thanks. I have only used it where enumerators might want to be able to zoom in on detail of a photo that is 'recognisable' on screen at standard resolution...
This is an understandable (data management / conflict) problem, but it does effectively negate the capability of editing submitted forms on a device if entities are involved - I was discussing this issue with a client only yesterday! These are the unintended consequences of enabling 'allow edits' - I got caught out on another project and had to do some nimble shuffling of data to 'rectify' a problem of my own making.
