Can I make this into a plugin/hook?
 

Hello,

I recently modified includes/class_image.php to customize the look of the human verification image.

When I went to upgrade I noticed that this file could easily be clobbered and so I started looking at how I might be able to make a change here without actually digging into the php code of vb.

I also had to chnage includes/class_humanverify_image.php

Can I turn these changes into a plugin? How do I go about doing this since I'm not seeing any kind of "hook" that I can attach this code to...

I'd appreciate any help as I'm looking to make the board easy to upgrade without needed to reimplement my hacks.

It depends what you are doing - have a look at the hook locations in that file, and see if you can make any use of them.

there arn't any hook locations in these files. I guess the verification image system isn't plugable?

I changed mine to garble the text but not rotate things as much. I had some people complain that they had a hard time reading it... and for me it wasn't worth users complaining but since I've had spammers I tried to fix it up to meet my needs... If I could make it into a plugin/product I could share it with everyone...

I presume its poor design to have the product installer inject code into a php file...
