I did not have any experience with GD::SecurityImage. Instead I implemented my
own Captcha logic in this web application of mine:
http://svn.berlios.de/svnroot/repos/web-cpan/WWW-OneTable-MiniReporter/trunk/
To see the changes, run the command:
svn diff -r 1724:1725 $URL
with the URL I gave.
Note that this is a simple textual captcha, but it was enough to completely
eliminate the spam postings to the IGLU Jobs database (
http://www.iglu.org.il/jobs/ ) so far. Image captchas are a huge
accessibility problem for sight-impaired people.
