Define the “own” wording?

Hello,

I build in the Captcha – all working well. But one question…I build in like this:

[f12_captcha captcha_sending captcha:image]

This creates also the field and picture, but within the field I have “Captcha” written. Is there any methode giving this an own naming? Something like this? Couldn’t find any documentation.

[f12_captcha captcha_sending captcha:image title="Enter Security Code"]

Thank you
