Write some Software

I need someone to add some functionality to a current website. The functionality will be to add media uploads to a page: Should allow multiple uploads from a single input. Works the same way as Facebook - add images. Upload files to specified location & add record to the database. Should show preview of images uploaded (as in screenshot) Should allow multiple images or 1 video (different icon for each) Should have validation to ensure criteria is met Should resize images to maximum sizes.
