plz help me...

URL of your site is?
Need to see product you are referring to.

i m attaching the product info page so that u can understand what i want.....

So why cannot you use attributes for choices?

my client doesnt want that.
as he has to enter attribute everytime for each product.so its seems to be a tedious task.

has to enter attribute everytime for each product
Not necessary.. it is possble, once attributes are set up, to
copy them from one product/category to another.

okie...
and what abt the radio button which will be display for selecting perticular attribute.
i dont want that radio button.i want add to cart image there.

You can set attributes to have images
i.e.
http://zencart.net/demo/index.php?main_page=product_info&cPath=23&products_id=84

NO its not like that....i dont want radio button .....i want to use image instead of that, so that when i choose image i can get related attribute in my cart.
u can see in my before attachment

Then you may need to recode certain zencart files..

i recode some files too i m able to get the perticular attribute in my cart.
but my problem is that suppose customer has selected small size image to download.n when he complete the process of checkout n payments r confirmed he should get file to download small image....
i having a problem in how to achieve this.

Each attribute should have it's own image assigned to it.
Will work better if you add image/s to zip file for attribute
chosen. So each image attribute has it's own zip file.
