Of course you can
Once you've bought the item then it's yours to do with what you wish.
If you want to use the photo or any part of the listing which you purchased the item from then you must ask the seller's permission first.
Much better to take your own photos and write your own listing.
If items are unsuitable or don't fit, then you are supposed to re-sell. Not try and make the seller accept the item back for a refund.
