Grant it's
NOT the forums fault!
it's simply the iOS causing all images uploaded to rename (on the device) to image.jpg..
thus the previous file with the same name will be overwritten with the latest.
that's common behaviour, and yes.. I think one could eventually build a plugin to rename all uploaded images (say add a counter 0-9 at the end)
to achieve that without much hassle for the user.
But the problem is the iDevice (IDK if androids do the same crap tbh)
it's apples fault; not vbulletins
And don't get me wrong, I'm using an iPhone and I likely stick to that myself.
But just google the issue itself, and you'll find metric tons of threads and support groups all over the world (many on apples support pages even)
addressing just that stupid behaviour (and it's not a bug... it's a FEATURE

).
it happens on every multifile upload script that's NOT custom tailored to fix this iOS issue by arbitrarily chaniging file names.
As if a numbered filename would cause any security issue
Truth is, this forum has no inbuild mobile-template which indeed is kindof a shame really.
but there IS a mobile template that renders just nicely on at least most mobile devices (without tapatalk or other plugins like that)
that STILL isn't fixing errors that are not caused by the forum but by the device you are using.
You cannot make a true "one for all" if not "all" devices follow the standards
