Our captcha image is very small and we're received complaints that it is too small to see. I wondered how we could make it bigger. It is currently 103x21 pixels. I can maybe edit the code if I knew where the size is specified in and if making it larger would still keep the image clear to see.

Hi Jason!
Sorry for my late answer.
Open the file components/com_comment/joscomment/captcha.php
look at this lines:
$bgurl = rand(1, 3);
$im = ImageCreateFromPNG("captcha/bg" . $bgurl . ".png");

ImageCreateFromPNG function will open one of the 3 png pictures in the folder captcha. Open this pictures and make them bigger.
Then you can look at this lines here:
$size = rand(12, 14);
$angle = rand(-4, 4);

Change the values and you will get for size - a bigger size
and for angle a different angle the text is shown :)
Cheers!
daniel
