Add New Tab to the magento order view to add attachments for each order and show these attachments into the customer accont page on front end so they can download them.

===============================

Create a Database table by running the following Query:

CREATE TABLE dev_magesf_ordercustom ( id_magesf_ordercustom int(10) NOT NULL, order_id int(10) NOT NULL, image_url varchar(155) NOT NULL, image_comments varchar(155) NOT NULL, customer_id int(10) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

ALTER TABLE dev_magesf_ordercustom ADD PRIMARY KEY (id_magesf_ordercustom);

ALTER TABLE dev_magesf_ordercustom MODIFY id_magesf_ordercustom int(10) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=10;
