Computerminds are proud to be members of the Drupal association and encourage all our clients to contribute as well. The Drupal association was established to help the Drupal community with funding, infrastructure, events, promotion and distribution. It has already made a significant difference to the invaluable drupal.org site with contributions of some lovely new hardware.
There is nothing worse than having your browsing flow interrupted by a login screen that does not return you to your origional destination. Drupal manages to get around this problem by allowing you to append a "destination=XXX" query string parameter to the 'user' login URL.
This is excellent and works well, except what happens if the user clicks the register tab while on the login screen - the destination query string is lost and the user has to resort to the back button.
This article applies to the current dev release of both the captcha and the textimage module. It involves modifying captcha.inc file which is distributed with the textimage module - it is therefore only a temporary solution and should be treated with caution!
