Was just about to post about exactly the same thing!
Multiple image / file picker, along with ability to show an array of image is a great addition,
But I have loads of images already stored in AIrtable and want to keep using that as my back end (for lots of other reasons) - not being able to upload multiple attachments is a pain.
Before I start doing crazy work arounds - is this likely to be added? In this post I can't use the multiple image in the image picker @david was unsure whether it would work or not
