What are the record keeping requirements for non-cash donations over $250, but under $500? If I attach a detailed list of items to a goodwill receipt is this enough?

I donated over $250 but under $500 multiple times and kept the donation receipts as well as pictures and a detailed list of items and values, the values are from it's deductible.
Is this enough documentation for the IRS? Or do i need to get something else from good will? If I do, how do I go about this?

The donation receipts have Charity, Date and Address only.
