Apple please allow us to change the IMG_ prefix in iOS
Me and my girlfriend have iPhones & iPads (well technically I dont have an iPhone yet), that would be 4 devices. We bought the devices at the same time so the chances of picture names overlapping is preety high.
I use Windows and my girlfriend too, and when we have to download files from our devices into our folder structures (which we share on the network) then some overwrite could occur if we are not really paying enough attention at the Overwrite? question.
