Selling images

I am new in this and I have one question/for suggest.
I try to sell images over opencart.

Here is my question I sell one picture dimensions 800*600, but I want to sell the same picture with dimensions 1200*900 and 2200*1600. Is it possible to add those two images as downloads opinion with different prices?
or some other solution, except to for every resolution to open new product/card.

I hope you understand me
best regards

I think you need separate products.

I would suggest you use product options, and modify the base price according to size.

Komir .. I agree with godologic , I would use product options. You would need to make some customizations to the downloads module to only show the appropriate download to the customer.

Also if your looking to setup a stock photography site you might be interested in my reward points module (see signature), it allows you to create a credit system where you can make products which provide points / and other products which require the use of points for purchase (similar to istockphoto and the like).

Assuming different resolutions have standard price points you may want to use quantity to somehow direct which version they would have access to (might be slighly easier than using options).
ex.
qty 1 = small
qty 2 = medium
qty 3 = large

Again that would require some level of customization .. it just might be easier then using options ...
