CAPTCHA Image Sets
Here are some tar.gz files (you
can open these with winzip for you windows people), of image sets
of about 1000 images each. Choose a set that is best for your
website. If you do not need a skewed or hard to read image, use
the plain clearly readable images. If you want top level security,
you can use one that is hard to read so the OCR systems will not
be able to read it.
All the sets are all capital
letters, but the program is not case insensitive. It is just
easier for people to read using capitalization. I plan to add
more sets with more variety but for now, its a good starting
You can mix the sets if you
want to. You can use the 6 character sets allong with 4 character
sets, number sets with word sets and so on. But I suggest you use
one set to keep it simple. Just click on the style you want to
use, save the zip file and upload the images to your captcha
image directory. You can replace your images at any time if you
want a fresh look or more security.
|Basic Mixed Sets
We added some dictionary words that will
make it easier for users to read as well as some basic number
sets. The random mixed text is often difficult for people to understand.
The number sequences and actual words are still bot proof and
offer a much more user friendly captcha system.
If you need a special image set, let us
know. We do not charge for custom images sets as long as you link
back to our captcha program from your website. There is no
guarantee we will have time to build custom image sets, but we
often create custom sets beyond this gallery.
