Create a post submitter with Javascript

I need a javascript based post submitter such as the one found here: [login to view URL] I do not need it connected to the PHP backend, however I need the layout done exactly as shown there. (You must connect with FB or register in order to see the post submission form). Requirements: - Main title, description, and tags same as in the boredpanda example - Ability to upload images - Each image will have two extra fields attached to it: - Headline - Description - Ability to select multiple images, when this is done, multiple fields for each image will be created - Ability to easily drag and drop images to the upload field ([login to view URL]) - Ability to rearrange images by dragging and dropping around - Ability to delete images - Ability to load previous post.. meaning it should be possible for fields to be dynamically loaded (from server-side)
