I have created a custom post type and I need to add multiple images to every single post, so I can create a loop and use them in a slider. So far my search on Google etc. has turned up nothing.
What's the cleanest way to add a metabox to the custom post type, so I can add images to the post and create a loop to display them in a slider/gallery?
"context"=>"normal"
to the rest of your arguments.
