Hi Glyn, You can indeed keep your domain name. Domain registration is a separate process to site building, so there's no risk of getting one stuck on a platform you don't want to use any more. Wix is great at walking you through the domain transfer process step by step when you sign up. There's an official video guide here if you'd like a sense of how it's done. Hope that's helpful! Ta, Fred
Similarly to adding almost anything to your site, to add a gallery, you use the add element again. Each gallery you will see will be different from each other. From professional looking galleries to the less so professional. Wherever you choose to place a gallery on your site, always make sure the images are appropriate for the page or your website.
