Hi Penguin. There is already a [url=http://forums.b2evolution.net/viewtopic.php?t=2976]captcha hack[/url], and in the next release there will be a captcha plugin. Having said that, there is no reason at all why your method won't work. I guess technically it's a bit easier since your server doesn't have to generate images on the fly, but that's only a technical guess.
What you do upon failure is up to you. I say send the visitor back to the comments page with their comment intact so they can try again - and again - and again - until they get it right or give up. Keep in mind the only people trying are real people. Spam-bots won't go through the effort. Er... real people that can see and allow images.
Anyway there's no reason why it won't work. I guess the only issue would be how can anyone and everyone out there get pre-made captcha images like that? Would you consider whipping up a hack/plugin that has a few hundred of these images available?
