I am using Joomla 1.5 with Virtue Mart (also latest version).

As the topic say we want to offer our customers customization for Wall Graphic

Beside normal products (different wall graphics) the user should have the possibility to generate his own individual design (we print people in different sizes up to real size).

For this matter he has to click on a button on the website to enter a generator.
The function of this generator is the same as be seen on the following website:

http://www.fathead.com/custom

Functions:
Upload your picture
choose the size (system should inform the user if the dimensions are to small for his chosen size. warning message that the quality will be lower if he will continue may appear - like: if dimensions are higher 3000x4000 px than user can choose "real size")
There might be a text area where the user can enter the dimensions of the human or object he want to get in real size. If a girl uploads a picture of her boy friend she has to add the information that the man is 1.80 m high for example.

Than the user has to decide if he want the picture contour fit or the hole poster with background. Here he has just to click on a radio button.

There might be an extra possibility to enter extended information into a comment box. The user knows the costs, from that moment he choose the size, so that he finally click on “add to cart” and he can go to pay for it.

The uploaded pictures and the information he chose have to be transferred into a database or to an email account or how ever.
