AdSanity – Image Cache Buster

AdSanity – Image Cache Buster is a WordPress add-on that appends a unique cache-clearing string to every ad image URL. This simple solution forces browsers and caching systems to load the latest version of each advertisement. The add-on prevents outdated images from displaying when you have already uploaded new creative assets.

Website performance optimization often relies on caching mechanisms. While caching follows best practices for speed, it can cause problems for advertising. Old image versions may persist in a visitor’s browser cache even after you update an ad. This issue becomes particularly noticeable with animated GIFs that stop animating or show stale frames. The Image Cache Buster solves this problem automatically.

The add-on requires no configuration or ongoing maintenance. You simply install and activate it alongside AdSanity Core. The plugin then handles all cache-busting operations in the background. Every time a visitor loads a page with an AdSanity image ad, the system adds a unique query string to the image URL. This string changes whenever you modify or replace the image file. The best part is that you can truly set it and forget it. All functions require the latest version of AdSanity Core.

Key Features

Automatic Query String Generation
The add-on appends a unique cache-busting parameter to each ad image URL. This string changes automatically when you update the image file.

Zero Configuration Required
No settings pages or options exist for this add-on. Installation immediately activates the cache-busting functionality across all image ads.

GIF Animation Preservation
The solution solves the common problem of animated GIFs that stop moving due to cached versions. Visitors always see the latest animation cycle.

Seamless Background Operation
The cache-clearing string generation runs without user intervention. You never need to manually clear caches or refresh assets after updating ads.

Browser Cache Override
Each image URL appears unique to browser caching systems. This forces browsers to download fresh copies instead of serving stored versions.

Core Plugin Requirement
The add-on extends the latest version of AdSanity Core. It works specifically with image-based advertisements managed through the primary plugin.
