In addition, a database can be used instead of +session storage. + +Variables within the class are used to control the style and display of the +image. The class uses TTF fonts and effects for strengthening the security of +the image. + +It also creates audible codes which are played for visually impared users. + +## UPGRADE NOTICE: + +**3.6.3 and below:** +Securimage 3.6.4 fixed a XSS vulnerability in example_form.ajax.php. It is +recommended to upgrade to the latest version or delete example_form.ajax.php +from the securimage directory on your website. + +**3.6.2 and above:** + +If you are upgrading to 3.6.2 or greater *AND* are using database storage, +the table structure has changed in 3.6.2 adding an audio_data column for +storing audio files in the database in order to support HTTP range +requests. Delete your tables and have Securimage recreate them or see +the function createDatabaseTables() in securimage.php for the new structure +depending on which database backend you are using and alter the tables as +needed. If using SQLite, just overwrite your existing securimage.sq3 file +with the one from this release. + +*If you are not using database tables for storage, ignore this notice.* + +## Copyright: +Script + Copyright (c) 2016 Drew Phillips + All rights reserved. + + Redistribution and use in source and binary forms, with or without + modification, are permitted provided that the following conditions are met: + + - Redistributions of source code must retain the above copyright notice, + this list of conditions and the following disclaimer. + - Redistributions in binary form must reproduce the above copyright notice, + this list of conditions and the following disclaimer in the documentation + and/or other materials provided with the distribution. + + THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" + AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE + IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE + ARE DISCLAIMED.
