Question 1

How to integrate Securimage with a database instead of PHP sessions?

Accepted Answer

Use the PDO support with databases like SQLite, MySQL, or PostgreSQL. Configure the database connection in the Securimage class, and it will automatically create tables and store CAPTCHA data, allowing for stateless operation as mentioned in the synopsis.

Question 2

Is Securimage or hCaptcha better for a small website?

Accepted Answer

Securimage offers self-hosting and customization, but hCaptcha is maintained and has better bot detection. For small sites needing low maintenance, hCaptcha is safer, while Securimage suits privacy-focused, custom setups if you can handle the risks.

Question 3

Can I use Securimage with Laravel or other PHP frameworks?

Accepted Answer

Yes, but it requires manual integration since it's a standalone class. You'll need to include the files and adjust configuration within your framework, which can be more complex than using framework-specific packages.

Question 4

What are the main alternatives now that Securimage is abandoned?

Accepted Answer

Consider external services like hCaptcha or reCAPTCHA for ease and security, or look for maintained PHP libraries on Packagist. Self-hosted forks might exist, but they lack official support.

Question 5

How to customize the CAPTCHA image colors and fonts?

Accepted Answer

Modify the Securimage class properties for image dimensions, fonts, colors, and distortion effects. The example form and README provide guidance on adjusting these settings to match your site's theme.

Question 6

Does Securimage work on mobile devices without Flash?

Accepted Answer

The image CAPTCHA functions, but audio CAPTCHA uses Flash, which isn't supported on most mobile browsers, so audio playback will fail, reducing accessibility for visually impaired users on mobile.

Question 7

Is it safe to use Securimage in production given past vulnerabilities?

Accepted Answer

While the latest version fixed known issues like XSS, the lack of maintenance means new vulnerabilities won't be patched. For critical applications, switch to a maintained alternative to ensure ongoing security.
