how to get my own class as library

[eluser]2think[/eluser]
Hi Said,

From my understanding of the user guide, helpers are more limited than libraries. Since you're talking about providing captcha image generation which may/may allow for more/different fonts, languages, etc. in the future, I would think a library would be the best fit.

As for incorporating it as a lib, check the user guide where there is a section with that very subject: http://ellislab.com/codeigniter/user-gui...aries.html

Best wishes.
