I have created a Custom Field for multiple Images, and I see that the "popup" is quite different to the one that appears when you try to add images to a Post or Page. I would like to be able to select several images at the same time. But instead I have to create a new field everytime I want a new image, and again select the new images. I have to repeat this process one by one, which makes it quite cumbersome. Is there a way to improve the User Experience?
Thank you
