In the WideRange admin control panel, there are three main ways to add a page to the website: you can do it via the Misc Pages, the Galleries, or the Products. Here I will explain the purposes and benefits of each.
Misc Pages
The Misc Pages section offers a simple way to add a simple page. This is a good place to add a simple, single page where you just have some text and a few photos interspersed in the text - such as perhaps an About page or a basic Prints Information page. You can just write your text and insert/upload a few images directly into the text.
Galleries
You might assume that the Galleries are just, well, photo galleries, and that their only purpose is display photos. However, the Galleries don't necessarily have to be photo galleries; they are fundamentally just pages too and you can actually leverage the galleries structure to create a hierarchy of any type of pages and sub-pages!
An example of this is actually all these WideRange Support articles you're reading right now! All these support articles and help topic pages were actually set up in the Galleries section of my admin panel, as a series of galleries and sub-gallery pages. Even though most of these pages don't even have any photos, I'm just using the galleries as text pages and leveraging the gallery structure in order to have the built-in gallery page layouts and sub-menu structures.
Another example is the Prints Info page on my photography site. I set this page up in the Galleries because I wanted to have several separate sub-gallery pages for each of the four print display styles I offer. So, the main Prints page is a gallery with a "Sub Galleries Tiled" format, then I created four sub-gallery pages underneath it for each of my display options.
The beauty of building pages in the Galleries section is that you can utilize all the built-in sub-gallery (or "submenu") formats to set up a series of linked pages like these examples above.
You might ask, though, "What if I don't want these pages to show up on my main Galleries page with all my other photo galleries?" No problem - just make the page a "hidden gallery", then it won't show up with the others, and you can link directly to it from the main navigation menu or elsewhere.
Products
What you might not realize right away is that each product that you add in the Products section of the admin is actually a page. Just like each Gallery is actually a page. Just as each Gallery gets a URL page address, so too do the Products get their own URL page addresses. The main difference here, though, is that Product pages can have prices (and thus, Add-to-Cart buttons).
Also similar to the Galleries, in the Products section you can set up a series products and sub-products, to have a hierarchy of product menu pages and sub-pages. The Products also have a variety of page formats you can choose from, just like the Galleries.
Just like with the Galleries, each Product page doesn't have to be an actual product - it can be used as a menu page of sub-products.
One common example use of the Products section is to create a Workshops product page, then create a series of sub-products under it for each actual workshop. The main Workshops product page would have a "Sub Products" type of page format, so it basically serves as the menu page of all the individual workshop products. Then each of the individual workshop product pages gets their own descriptive text and prices, and can be added to the cart for checkout.
The Products section can be used to set up pages for any items you want to sell: workshops, calendars, books, etc. Basically, pages for anything you want to sell should be set up in the Products section (besides prints, since those are managed in the Prints section).
