graphics and pasting

i have a small web site that sells sports items,it used to be quite big but the franchise i purchased went out of business so now i have a inventory in my home and ship out of it.i recently have joined with a company that gives you products to sell on your site as well as another site of your own called excel.they have lots of sports products that are on the home site they give you.what i want to do is transfer the graphics over to my sporttz.com site .and do business from my site.when i do a copy paste over to my site just testing not all the graphics show up all the time.i realize its just a link back to the original site but i m just looking for the best way to get the sports items over to my site intact.is this the best way to do this and what other problems could i face.
