I just saw an example of images including a captcha and thought it would be a cool little feature to add. It seems it is a whole new area of php though and don't think I'm up to that task just yet. Just wanted some advice on the most common features of PHP images.
Could you explain in laymans terms about the concept of an overlay? Is it the same as when you go on an image site and they print their name/logo onto the front to prevent people from stealing them?
Cheers for the reply.
