It is to prevent bot program from executing interactive user process automatically...

Having verification code will required us to identify and key in what was interpreted by our eyes before the website will proceed to process our request.

E.g. to prevent bot program from registering as KT member so as to spam large number of threads/posts effortlessly.

I could not explain for that because it is algorithm of the verification code generator which created the image... the alphabet/number image could have been hardcoded, or the the generator retrieved from a standard set of alphabets/numeric images to generate as a single image

If you can't read it, you can choose to regenerate the picture, I believe most websites have a button that does that. For those who really cannot see, some websites give an alternative to play a sound for you to identify. I've never used that function before so I don't know if its easier.

:laugh: i dun think is warning lah, more like reminding you to check back on this thread whether your question was answered correctly or not.

If still not answered or not understood, then it is best that you ask for more clarifications or ask for more opinions.
