Settings reference

Every setting on the Settings tab, what it changes, and what it defaults to.

URLs

Archive slug	The archive URL. Default `photos`, giving `/photos/`.
Item slug	The URL for one item. Default `gallery-item` on installs made with 3.11 or newer; sites that installed earlier keep `photo`.

Change either and visit Settings › Permalinks, then Save, once. Otherwise both URLs return 404.

Archive page

The heading in the admin shows the archive URL in effect.

Use a saved display	Replace the built-in archive with one of your displays. Default: built-in.
Items per page	Default 24.
Columns	1 to 8. Default 4.
Open in lightbox instead of item page	Off by default.

Images shown publicly

Largest size shown publicly	Caps the lightbox, the item page and the srcset, so the original file never appears in the page. Default `large`.

Watermark PRO

Watermark	Off, Text or Image. Default off.
Watermark text	Up to 60 characters.
Watermark image	A PNG with transparency from the Media Library.
Position	Nine positions plus tiled. Default bottom right.
Opacity	5–100. Default 55.
Size	5–90 percent of photo width. Default 25.
Margin	0–20 percent. Default 3.

See Protecting your photos.

Item page layout

Nine cards; click one and save. Classic, Stacked and Minimal are in the free plugin; Card, Hero, Catalog, Sidebar, Filmstrip and Editorial come with Pro and appear only when it is active. Default Classic. Only a save made from this screen can change the layout, so saving from anywhere else never resets it. See Single item pages.

Single item page

Related items	How many to show. 0 turns the section off. Default 6.
Related by field	Which field decides relatedness, and names the section heading (Related by Album). Default People.
Show previous / next links	Off by default.
Allow comments on item pages	Off by default. Covers every item at once, including items created before a change under Settings › Discussion, which only reaches items added afterwards.

Downloads & selling PRO

Download size	Which registered size a download serves. Default `full`, which is the clean original.
Currency symbol	Default `$`.
Note under Buy button	One line of small print. Empty by default.
Buy button colour / on hover	Optional. Blank keeps the standard dark button. The text turns light or dark automatically.
Archive page: checkboxes to download several items at once	On by default, but only visible where items are actually downloadable.

See Downloads and selling.

Uploads

Automatically add every image uploaded anywhere in WordPress	Off by default. Only sensible on a site that is purely a photo archive.

Uninstall

Delete all gallery data when this plugin is deleted	Off by default. With it off, deleting the plugin leaves your items, fields, displays and settings in the database.

Your image files in the Media Library are never touched either way.

Settings that are not here

Gallery layout, captions, visitor controls, backgrounds, hover effects and download buttons are all per-display, not global, and live in the display builder. Which fields exist, and where each one appears, live on the Fields screen.
