We've used several other captcha plugins but SecurImage has been the most reliable to implement and easiest for site users. Some others we've tried don't reliably display on the page or are difficult for some users to read. We had a site-specific issue with the code refresh if a user entered it incorrectly, and Douglas sorted it out very quickly and sent us an update. Developing on Joomla since 2006, I've used hundreds of extensions. Douglas is one of the most professional and prompt developers I've had the pleasure to do business with. Thanks for your work!

I use Securimages as my default spam stop - it's as easy to use (and as effective) as spam protection gets. Install, turn on...and you're done! I always use this paired with the Contact Enhanced component (five stars!) from the same developer. Either or both are highly recommended.

Worked fantastic,has lots of options, took 1 minute to configure and perfect.
When i updated from joomla 3.2.1 to 3.2.2 and updated a few other components as well, and had a small conflict with another components update. I emailed support and Douglas replied within 30 min, asked for a bit more info, and had a new adjusted plugin emailed to me within an hour, and it wasn't even his plugin that was at fault. A nice guy to work with and excellent support. Thank you again Douglas

Although this is a very easy to configure plugin, it offers many options to customize it.

This is yet another great extension from Ideal Extensions that leaves little doubt Douglas knows his stuff. I've installed this extension on a clients new website and was thoroughly impressed with its easy of configuration and implementation. Support is near instantaneous, courteous and friendly. Having been a Joomla site developer for some years now, anything from Ideal Extensions is a "must have" that never fails to save hours and hours of time. 6 stars to Ideal Extensions!

Installed it yesterday and already have 50+ bots registration.

No issues from real visitors, but too many bots registration.
Owner's reply

Dear ErikF,

SecurImage protects your forms against spam bots. There are several settings on the back-end in order to make it harder for spam bots to guess the image code.

If the problem is with registration, please check if you have other extensions that allow user registration. Some Forums (like Kunena) and shopping carts do not use Joomla core Captcha plugin type, therefore SecurImage captcha plugin cannot protect it.

If that's the case, please contact the other extension's developer about it and please change your review. Otherwise, contact me, so we can work together on a solution.

Best wishes,

i hate recaptcha as its so hard to decipher and i am sure i loose users that just give up on it - because its so integrated into joomla for lots of extensions, i just had to use it... UNTIL NOW...
thanks to securimages i have all the build in functions as recaptha, but without the craptcha!

thanks for brilliant extension and well worth the 6 bucks(R63 for me in South Africa)

I never belived about this plugin, is very simple to use, but it's security for my website.
The support is super fast.

Used reCaptcha before, but the sound is poor and, most of all, it kills my mobile templates.
SecurImage is the ultimate solution.
You can customize it much better and easier than reCaptcha.
And... support is faster than lightning. And all this for such a small cost, it's very satisfying.

SecurImages is a gem of a plug-in. I particularly admire its option to set up for your Joomla registration a mathematical captcha. Also, support from Douglas is very prompt, friendly and professional.

Keep up the good work, Douglas ;)
