Question about item descriptions and stock photos for website

[markw10]

I am close to launching a new e-commerce website.
My question, where should I get the item descriptions and photos that are used for the items on my web site? I currently have an eBay store and have been mostly getting these stock descriptions and photos from either the company that makes the product or either the supplier/distributor that I purchased the product from.
I just want to make sure that there are no legal issues involved or even if there are services or places I can subscribe to to get this information. The products that I will be selling are video games and accessories, audio/video products and accessories, computer accessories, notebook computers, and also we sell a lot of books. Thanks for help with this.
