Pro features overview ​

Ultimate Watermark Pro is a single plugin that adds about a half-dozen modules to the free core. Activating Pro unlocks every module — there's no per-feature toggle on the website. Modules expose their settings inside the watermark template builder (a new Display tab) and on the Settings page (a new Advanced (Pro) tab).

Templates ​

Unlimited templates ​

Free is limited to one active watermark template (WatermarkAjaxHandler.php:608–620). Pro removes the limit — make as many as you need:

  • A copyright text watermark for blog posts.
  • A logo watermark for product photos.
  • A "DRAFT" diagonal stamp for work-in-progress uploads.
  • Different watermarks per WooCommerce product category.

All run on every upload; conditional rules decide which ones actually apply.

Dynamic content ​

Dynamic placeholders ​

Embed {{placeholder}} tokens inside text watermarks. Pro replaces them at render time:

PlaceholderReplaces with
{{date}}Current date in WP date format.
{{time}}Current time.
{{year}}Current year.
{{user}}Logged-in viewer's display name (or empty for guests).
{{user_login}}Logged-in viewer's username.
{{ip}}Visitor's IP address (deters re-publishing).
{{copyright}}© plus year and site name (see plugin output).
{{post_title}}Title of the post the image is attached to.
{{site_name}}Site title from Settings → General.
{{site_url}}home_url().

Use cases:

  • A "© 2026 Studio Name — viewed by John on 12 Mar 2026" diagonal stamp deters image reposting.
  • A "Draft for {{post_title}}" stamp on staging uploads.

Resolved via ProPlugin::processDynamicContent (ProPlugin.php:160–194) and DynamicContentManager::parseTemplate.

Custom placeholders ​

Register your own with the ultimate_watermark_pro_register_dynamic_types action and ultimate_watermark_pro_resolve_placeholder filter. See Hooks & filters → Dynamic content.

Frontend display ​

On-the-fly (OTF) rendering ​

The flagship Pro feature. Instead of burning the watermark into the file on disk, Pro renders it at request time and serves the result.

Why this matters:

  • Originals stay clean — the file on disk is never modified. Useful for stock photographers who need pristine masters.
  • Edit-and-go — change the watermark template, hit Save, the next visitor sees the new version. No bulk re-process.
  • Cached output — the rendered watermarked image is cached at uploads/ultimate-watermark-frontend-cache/. Subsequent visitors hit the cache. (FrontendWatermarkManager.php:407–418)

Set up: edit the watermark → Display tab → toggle on. See Settings → Display tab for every option.

Role-based bypass ​

Pro lets you bypass the watermark for specific roles — useful for editors who need to copy images out without watermarks. Default bypass: Administrator.

Conditional rules ​

Advanced rule types ​

Pro adds 9+ new rule types beyond the free post-type / image-size:

  • File type (MIME).
  • Image width / height.
  • File size.
  • Image orientation.
  • Image aspect ratio.
  • Date range.
  • Post category.
  • WooCommerce product_cat / product_tag (when WC is active).

See Conditional rules for setup and recipes.

E-commerce ​

WooCommerce integration ​

The EcommerceManager module (EcommerceManager.php) hooks into WooCommerce:

  • Product images are watermarked on upload.
  • Product gallery images are watermarked.
  • A bulk action in WooCommerce → Products lets you re-apply / remove watermark for selected products.
  • The OTF Display tab has a dedicated Apply to WooCommerce toggle.
  • Conditional rules can match product_cat and product_tag.
  • Bulk batches process at 5 products per pass (EcommerceManager.php:335–339) to fit shared-host limits.

Settings live under Watermark → Settings → Advanced (Pro) (ProAdminManager.php:1471–1489).

Performance ​

Background batch processing ​

For libraries with thousands of images, Pro queues work via wp_schedule_single_event and processes in chunks of 10 (BatchManager.php:76–78,110–112). The admin shows a progress UI; you can leave the page and it keeps running.

See Performance → Background batch.

License & updates ​

License manager ​

Activate / deactivate / check status against https://store.mantrabrain.com/edd-sl-api/? (item_id 36499 — License.php:31). Pro updates show up in Plugins → Installed Plugins when license is active. Daily license check runs in the background.

Activation: Watermark → License (ProAdminManager.php:75–81).

Plan tiers ​

Ultimate Watermark Pro is sold as a single tier — every active license unlocks every Pro module above. Pricing options differ on license seats and renewal terms.

EDD's price_id=1 is the visible price ID in code (WatermarkActionsHandler.php:75). For current seats and renewal terms, see the pricing page.
