Fox_captcha version 2.5 is released. It has a bug fix and a new feature.
The bug is wrong number for rendered lines which is controlled via $lines_amount property and it set by default to 5 lines. It was shown more than 5 lines and setting $lines_amount to any value does not leads to change in the lines numbers for reloaded image.
The feature is displaying animated gif image for indicating to downloading new Captcha image.
