I'm thinking about opening a large online store for Jewelry, the one thing that really bothers me is managing the actual operation of taking pictures, uploading and describing all the products.

I'm trying to figure out the best way to do it, in terms of performance or the least time consuming.

Just a few things to keep in mind

1. I'll have over 1,000 items in the online store
2. I'll have 3-4 pictures for each item, I'm using a DSLR camera if it makes any difference.
3. I'm going to probably use Magento, unless you have better experience with another eCommerce platform that will help me get this done quickly.
4. I'll need to randomly(?) create a product code for each item.
