Fixing the gem issue on photos

The option to spend gems on photos needs to be more secure rather than just tapping on it, adding some sort of confirmation before purchasing would be a great help! Myself and many others have accidentally clicked on the picture whilst in a convo with a character, it becomes quite annoying as most of us save our gems for when our favourite characters come back and all the work put into saving disappears. Please find some way to fix this small but very significant mechanic.
