How to make a design page for Tshirt

HEllo, I would like to make a design page that user can design his Tshirt online. It should have the functions like, adding pictures or text on the Tshirt, and the user can modify the font of the text and the position of the picture. After design, the whole information should be sent to the database for producer usage. SO could any one have some good suggestion or source code for these purpose or any good links.

There is a similar function link. http://www.99dogs.com/custom2.html It is the whole process of the design and contains flash. So could any expert help me to achieve these functions in my design page. It is urgent and very important for me. Many thanks in advance!

Flash is perfect for this kind of thing. It'd be a nightmare, but possible, to do it using DHTML.

Thanks for your suggestion. Yes, flash is a good idea to achieve these purpose but because I am just a beginner and would like to know the related knowledge of flash for this task of design page. IF you have any idea, could u give some detailed help. Thanks again in advance!

Well, it's a difficult thing to build if you're a beginner.

Unfortunately, you'll either have to pay someone to do it for you, or slug it out yourself.

well, good suggestion and can u do it? and how big award do you expect? everything is negotiable, is not it?

Unfortunately my plate is rather full at the moment. Plus I'd recommend you write the app in Flash, which isn't one of my skills.
If you want the app written properly and professionally, I'd recommend you post your requirements at an online freelancing board like elance.com
