Hi guys, i'm semi knowledgeable in php. I'm currently working on to my project in school. I encounter this GD library which is really cool. I'm planning to create my own customize captcha but unfortunately this is my first time to encounter this feature of PHP. I'm wondering if i can create an image with some of words of it using GD library.. thanks!
wow thanks a lot. Much appreciated your effort and concern.. I learned something.. Thank you so much!!
I kind of like the sprite captcha idea. In order for a bot to defeat it the program has to read the letters and know where they are in the graphic and also be able to handle the css. I doubt any OCR programs will tell them where each letter is in the image.
I made it generate white on white because all an anti-captcha would need to do is a little image processing to remove every color except the #2 most frequent colors to get just the text and background.
