http://opensource.org/licenses/gpl-license.php GNU General Public License v2 Adds a new kind of Visual Confirmation, also known as a CAPTCHA, to phpBB 3. The person presented with a confirmation prompt must look at photographs and determine if they fit in a certain category or not. Jeremy Rogers Thoul http://www.phpbbsmith.com Josh Yelon Josh Yelon 2.0.2 easy 120 3.0.7-pl 2010-04-01 2.0.1 Fixed a display issue with the confirmation prompt on posting and login. Improved randomization in image set selections. 2010-03-27 2.0.0 Recoded to work with new phpBB captcha plugin system. This includes removing several things that were no longer needed, such as the UMIL installer. Added support for more than two sets of images. 2009-06-12 1.1.2 Modified install Find instructions for phpBB 3.0.5. (Applies to new installs only.) Added note to clear browser cache to instructions, due to cached ACP stylesheets making the preview look wonky. Added default mode setting, for better integration with modifications that use captchas, like Contact Board Administration. Borrowed the new wave transformation from phpBB's default captcha. Added new grayscale, interlace, and noise functions. Rewrote much of ACP interface for easier expansion in the future. Rotation and colorize settings are now a 1 in X chance. Image transformations are now listed in the order they are applied. No configuration changes are saved when an error is encountered. In the past, all changes except those triggering the error were saved. Added admin log entry on configuration update. On configuration change errors, the messages are displayed inline. Added ACP form token. Replaced installer with UMIL installer. Added integration install instructions for Contact Admin. Removed old upgrade instructions that are not supported by the new installer. Fix: Non-functioning rotation and mirror previews on lower PHP versions. Fix: Blank page errors resulting from including photo.php twice when a login form is displayed by posting.php. Fix: Removed dependency on phpBB 3.0.4's user->lang() due to too many forums having incomplete 3.0.4 upgrades. Fix: Replaced image selection method. Should hopefully end any residual problems due to file permission restrictions and perform better. 2009-04-03 1.1.1 Added configuration options for the new image transformations added last version. Improved handling of settings in ACP preview. Improved exit handling on image errors. 2009-03-21 1.1.0 Consolidated functions.php into photo.php, removed functions.php. Rewrites of code added to most files to make installation more concise. Removed change to language file, merged it with the modification's lang file. Added new template files to hold the HTML used. Added label HTML tags, so the pictures can be clicked to select them. (Note: doesn't work in Internet Explorer 7. That's browser bug, nothing I can do.) Replaced table layout of confirm images with lists on prosilver. Bug fix for broken images on systems with restrictive PHP safe_mode and open_basedir settings. Added per-instance width and height settings for output images. Added rotation option. Added a whole host of other new image transformations, which are randomly applied if available. Some require PHP 5 and/or that PHP uses the bundled version of the GD library. If these transformations are not available, they will simply not be used. The ACP preview is now run off the same code as the regular CAPTCHA, so if one displays, both will display. The ACP preview can now preview post and login settings. Changed location of ACP template files. Added error message when setting more than 32 photos on a prompt in the ACP. That is the limit, due to database restrictions. 2007-07-11 1.0.0 Updated for phpBB 3 RC 3. Removed edit to language/en/acp/common.php (no longer needed in RC3). Changed some include()s to include_once()s to potentially cut down processing time in ACP. Renamed the language file from photo_captcha.php to info_acp_photo_captcha.php. 2007-06-04 0.6.0 Moved the HTML for the confirm images to new template files. Added subsilver2 support. Adjusted the confirm code explain message to include a contact link. Tweaked the edit to prosilver's ucp_register.html to display only one explain message. Added version number in database. Added includes/captcha/photo.php to list of included files; it was accidentally left out. 2007-06-01 0.5.0 Initial port of phpBB 2 version. subsilver2
