Your server might not meet all the requirements for image text.
Run the test: /wp-content/plugins/si-captcha-for-wordpress/captcha-secureimage/test/index.php
What is the URL to your blog?
It’s http://josiah.angelorphan.com .
But my result was
PHP Version: 4.4.4
System: Linux
GD Support: Yes!
GD Version: bundled (2.0.28 compatible)
TTF Support (FreeType): Yes!
JPEG Support: Yes!
PNG Support: Yes!
GIF Read Support: Yes!
GIF Create Support: Yes!
mmm…
make sure elephant.ttf is in the captcha-secureimage directory.
It could be unreadable, or perhaps corrupted.
From the admin plugins menu, try plugin deactivate, then click delete. Install it again. See if that fixed it
PHP 4.4.4 is really old. Perhaps it is the cause. You should upgrade for security reasons anyway.
PHP 5.3 is current and more secure.
Thank you for advice,
I reinstalled plugin,but still I cannot see letters.
(and I had to write I don’t have any knowlidge about PHP and sometime cannot understand especially daily-use English.Sorry if I wrote something big-mouth.)
I checked my server’s manual(rental)and found I can use PHPver 5.2.8 using .htaccess file.(It’s newest on this server)
It takes time for me to avoid losing data,(maybe?)
Also,I use too many plugin for fun.I’ll reduce them.
I’ll report again after these task.
Thank you!!
It worked with PHP 5.2.8. it was easy,only upload .htaccess file which can download from my server’s support.
I appreciate quick and detailed advice.

Hello, glad you got it working. The problem with some older PHP and GD version is that they cannot do transparent TTF text properly so nothing shows up.
It can be resolved by turning off the transparent text option.
I’m so sorry it took time to change topic title as resolved.
I wondered I can change title or not..(Too new for WordPress world)
drew,Thanks for additional explanations.It works for me to learning.
–Resolved—
anybody else having this problem …
Try this:
edit plugins/si-captcha-for-wordpress/captcha-secureimage/securimage_show_medium.php
change:
$img->use_transparent_text = true;
to:
$img->use_transparent_text = false;
let me know if it works.
If this fixes it. I will try a fix that can auto detect if your PHP
can do the transparent or not. I would need you to try it for me, so be sure to contact me.

If you have this problem, try version 2.2.7 or higher and set the setting
“Disable CAPTCHA transparent text”.
Note: If the CAPTCHA image is missing the text, go to the plugin settings and check the setting “Disable CAPTCHA transparent text”. It will not fix it on the test page, but it might fix it on the wordpress forms.
== Changelog ==
= 2.2.7 =
– (31 Dec 2009) – New setting for a few people why had problems with the text transparency “Disable CAPTCHA transparent text (only if captcha text is missing on the image, try this)”.
