I am looking for a way to create a custom field/metabox that allow to attach multiple and infinite images to a post. This would allow to create a custom post type for a portfolio and allow to attach images without pasting them inside the post textarea.
Most plugins I've seen allow for only 1 image. I've got the inspiration from the awesome ProcessWire CMS, that allows for this functionality right out of the box. It would be awesome to have this in Wordpress too!
Is there a plugin I'm missing? Could this be done?
