PS There is some bug... js-error appears when displaying normal_image - new window with large image doesn't open by click (MSIE 5.5). But if captcha-plugin installed as described in http://forum.coppermine-gallery.net/index.php?topic=29564.0 everything is OK.

@Nibbler:
I don't know how bots deal with forms !
plugin will disable  OK button until you enter correct code and then it will become enable

@Nibbler: I've got your point , Bots can simply using myform.submit() command so I should use server-side code verification

Bots don't use javascript atall. You can use the page_start hook to check for the comment being posted and verify it from there.

Still no good. You need to check for the comment being submitted, not the code.

checking of $_POST['msg_body'] could be enough?
As I see under orginal mod Abbas checked $_POST['event'] instead

Hello, thanx for great plugin. Do you think it will be possible to do confirmation for not registered users only?
