Hi Don, welcome to SaleHoo!
Yes, you can get both the pictures and descriptions from the suppliers site. Most (if not all) dropshippers will assist you with this. You can also use photobucket.com, there are many product pictures available there.
The concept of listing products directly from the dropshipperâ€™s site to your listing/store sounds very appealing, we do NOT recommend it. Why? Because you have absolutely no way of standing out from the hundreds of other sellers using the same pictures/descriptions to sell the exact same products!
If your titles are the same, your pictures are the same, your description is the same, the shipping and service is the same â€“ what is your competitive advantage? Where is your unique selling point?
You might get a couple of sales if you are lucky, but itâ€™s not a workable model for building an ongoing profitable venture.
Thatâ€™s just our 2 cents :)
