Well, a few things can happen. Absolutely, your gallery link will be dissabled. There is a $15 fee to reupload it. However, I do not ever guarantee that I will have your link again, after sending it the first time. Not only, after a certain amount of time, do I delete galleries to make room for other ones, but over the years, I’ve come to find that not all external drives are reliable. I’ve had 2 of my very own, crash and break down, taking with it, many of my beautiful galleries. Thank God, none of them were ones I hadn’t given to my clients yet, but it still crushed my heart. With that, I say, download these images somewhere SAFE, possibly to a cloud or somewhere online. I offer no 100% guarantee that I will have them forever.
