Do I need to edit theme templates to use this plugin?

No. If you enable "Classes for automatic caching" and add the relevant CSS classes to the list, the plugin automatically replaces matching tags in post content and featured images. For full control, use the shortcode or PHP functions in your templates.

Frequently Asked Questions

Common questions about KDA Thumbnails

The plugin auto-detects Imagick first, then falls back to GD. You can force a specific engine on the settings page. Both must be enabled in PHP.

They are disabled by default. Enable "Allow remote image sources" on the settings page to cache external http(s) images. Remote fetching is protected against SSRF (only public IPs, default ports, no self-reference) and limited by a configurable max file size and TTL. Originals in the Media Library are still the recommended source.

A curated list is offered in the settings (Roboto, Open Sans, Lato, Montserrat, PT Sans, PT Serif, Oswald, Raleway, Merriweather, Roboto Condensed, Noto Sans, Ubuntu, Playfair Display, Titillium Web). The TrueType file is fetched from the public google/fonts repository on GitHub, downloaded once, and cached locally under wp-content/uploads/kda-thumbnails-fonts/. You can instead point the watermark at any local .ttf/.otf file.

When set to a value greater than 0, the copyright text is drawn with a colored outline (stroke) around each letter. The outline width is in pixels. This keeps the text readable on both light and dark areas of a photo. Works with both GD and Imagick engines.

Set "Cache size limit (MB)" to a value greater than 0. When the cache grows beyond the limit, the oldest cached thumbnails (by modification time) are removed automatically вЂ” both on a daily cron and after new thumbnails are generated. Set 0 for unlimited.

Use the "Clear all cache" button on the settings page, or clear individual post-type folders when "Organize cache by post type" is enabled. You can also call KDATH_Thumbnail_Cache::clear_all() programmatically.

Never. Originals in the Media Library are left untouched; only cached copies are created.

No. If you enable "Classes for automatic caching" and add the relevant CSS classes to the list, the plugin automatically replaces matching <img> tags in post content and featured images. For full control, use the shortcode or PHP functions in your templates.

Yes. The global "Output format" setting applies to all thumbnails by default, but you can override it per-request with the format parameter in the shortcode or PHP functions.

Yes. WebP is supported for both output (when selected as the format) and as a source image (GD with imagecreatefromwebp, Imagick natively). The plugin checks for WebP support at runtime and falls back gracefully if the engine does not support it.
