I really appreciate the plugin that you have made available. I am using this plugin on two different sites, one for our church and one for our radio station and both are having problems with the Captcha image. In Firefox 3.6.3, on our radio station site, there is no image and when you click on the refresh button nothing happens, if you click on the speaker icon to listen it gives a 500 Internal Server error. In IE8 it shows a box with a red "X" where the image should be. On our churches site, in Firefox 3.6.3, it is the same except if you click the speaker icon, it takes you to the home page. It does the same in IE8. If I click on the test link in the admin panel it takes me to the site home page as well. Here is links for both of our sites:
