Hi, I have had textimage working fine, except that it seems to need between 3-5 attempts before an apparently correct answer is accepted. I'm faiirly sure correct responses are being given each time - at least I have been very careful to respond correctly in testing. I am using the default font.

OTOH this may be by design, to test human patience? :-)

I experienced the same (drupal 4.7). Also, it seems sometimes (a part of) a character falls outside the image. Would be nice if this could be solved.

I had to give up with the image Captcha and revert to the math question, after complaints from users that correct responses were not being accepted until the 3rd, 4th or 5th attempt. Nobody managed to post at the first or second attempt, but also, nobody needed more than 5 attempts. This is so consistent I wonder if it's a deliberate feature to deter spammers. Unfortunately it seems to deter users as well.

I have same issue, the captcha + text image (or just the math) always responds with an incorrect error but the user's entry is added to the guestbook. I'm using the latest versions for 4.7 of both.

I've had the same problems with 5.x-1.1, and found the following fices. (The problem code looks to be the same in 5.x-2.0-beta so the same fixes should work there too.)

In a test I tried to enter comments ten times on a page with an image capture. Six times the captcha was rejected.

Five times it was because not all the captcha-string had been displayed. eg if the string was six characters long, only four characters had been shown to the user. The fix for this is described at: http://drupal.org/node/77554

The sixth time was because the string included an "m", but when it was displayed in the image it appeared to be an "n". The fix for this is described at: http://drupal.org/node/153773
