145460 Font Previewer Clone

I need you to develop an effect similar to the one found on: [login to view URL] Where it says "Type your text here" and when you type it, it displays your string in a png below the text box. Honestly, it doesn't have to be as high tech as MyFonts if that will take too much time (I would really like it to be though). Them simply typing the string and clicking submit and having the image display the string is acceptable as well. The only thing that is not acceptable is the actual page reloading/refreshing on submit, if it was that easy I would have done it :) The script should easily pull the font to be previewed from a $font variable which my own script will define. I'd also like for it to register their string to a cookie that expires in 1 day, so that as they browse through my website all of the font preview boxes will display their string by default. If the cookie isn't set the default text should be: AaBbCcDdEe Post on the PMB if you need clarification, it's pretty straight forward and simple, you don't need to implement it into the website or make it look sexy, it only needs to work.
