Working on this one - I used a clean install of 3.6.4 and have the same problem, will get back with an update very soon.

that worked!!!! thank you for sticking to it and solving the issue!! now i feel like my site is more secure....!!!

thanks very much for being so attentive to the issue!

It looks like you don't have GD Libraries installed, the images are processed through that for security reasons - unfortunately at this point there's no way around it - if you run your own server it's possible to get this installed fairly easily or maybe ask your ISP if they can install it for you.

Sorry I can be of more help.

You will need to check if you have GD installed - you can check this in the AdminCP -> Maintanence -> View PHP Info then scroll down and find GD - image attached to show if it is installed and working.

This is a requirement of the script to secure the images from being read.

Yup, installed and working for me.

I would like to install this but I don't see show.php anyplace in my tree. What is it, how do I get it, and what location should it be in?

Thanks!!!!!

show.php should be in same directory as your "verification" folder is..

/forum-root/images/verification <-there you should have .htaccess and show.php and all the images used for verification.

Based on your research, what's your opinion of this hack: https://vborg.vbsupport.ru/showthread.php?t=124828 which asks an admin-defined, forum-specific random question? Which way is better to go. Can/should we install both?
