Thanks to the author!
I spent more time on the registration process to download the extension than installing it and getting it working... (registration failed several times, but, at least, I could create an account to download the plugin).
Thank you, developer :)
Sorry you had problems registering. This was probably down to me upgrading the site to the latest Joomla core. Due to my using SecurityImages the registration broke, and it took me a while to realise, then fix it. Hopefully it is all fixed now - there is no captcha on the site anymore as I am relying on my other plugin to prevent unwanted registrations!
