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.
On the slideshow you will get the option to manage the slides. To edit the images o your slide show, click through the slides and choose slide background. You can choose from your own library of images, WIX’s own and even set it as a colour. Different slides will also have different features within them such as boxes and buttons. In the background settings of the images, always use scale to fit unless you want it otherwise. You can also choose for the slideshow to auto play, how long a slide shows for and other options.
The buttons/arrows which users can use to move from slide to slide can be edited also within the settings. These can be edited to match your websites theme. An animation can be set for the slideshow. This is how the slides come into view. Most animations are a bit crazy and swirl into screen whereas some are more professional and come into view gently and appropriately for a professional website. To edit any text on the slideshow, just double click on any text. Buttons can be direct to other pages of the website or other websites, both using a URL/web address.
A perfect example would be a photographers portfolio website. They may have different pages for different types of photos such as nature, cars even maybe something small such as street signs. Having a car page would mean, no images of nature should be in the gallery of the car page, unless the photo over laps each category. Then the photo could be an exception.
