Please go to ([login to view URL]). Choose a design. Then choose a template. It will take you to a page where you have to put the Headline Text. This site uses a module that extract images from the font installed on the server. And these images are used when the visitor creates a custom message. I need the script that extract images from the font and create an image based on the text inputted in the Headline Text. So basically, I want to copy the custom message feature of snailers.com.
