Photo Editing

I have photos in raw format (beginning with 12 or 13 pictures). I'd like them adjusted for brightness, contrast, etc., the background removed and the product copied and pasted on a background then saved as a jpg. All pictures will then need to be copied in a thumbnail size. Finally, upload full size and thumbnail images to Google drive. Prefer that this is done in PhotoShop (where batch features can be used for re-sizing). If this goes well there is potential for additional work on websites in the future.
