I need a plugin for custom post type. I need something like this:
Can anyone suggest a plugin which has this feature, especially image upload and "Add another" button option.
This metabox class does exactly what you are after and so much more.
This isn't a custom post issue - it's custom fields. You can use the Custom Field Template plugin to give you this functionality
I created the Meta Box Script that let us create custom meta boxes in WordPress. I go in a different way from WPAlchemy (yes, it's worth taking a look) as I think it's easier for developers.
