Australcode Uniform Images solves the classic WooCommerce catalog problem: product photos with different proportions that the theme crops brutally to align the grid. This plugin makes them uniform without cropping — it adds smart padding over a colored canvas (white by default), optionally trims the uniform background first to normalize inconsistent margins, and delivers each thumbnail in AVIF + WebP + JPEG using the <code><picture></code> element.
<h4>Key differentiators</h4>
<ul>
<li>No accidental crops — the entire product fits inside the thumbnail, always. Compare with “smart crop” plugins that guess the subject and sometimes fail on small or asymmetric products.</li>
<li>Real <code><picture></code> markup — multi-source with AVIF + WebP + JPEG fallback. Survives any page cache (LiteSpeed, WP Rocket, Cloudflare APO, W3 Total Cache) because it does not use <code>Vary: Accept</code>. The browser picks the optimal format; the cache serves HTML without negotiation.</li>
<li>4-tier quality preset — Maximum / High / Standard / Economy with per-format values calibrated (e.g. Standard = AVIF Q60, WebP Q82, JPEG Q85 — visually indistinguishable from the original at half the size).</li>
<li>HPOS-ready from day one — declares <code>custom_order_tables</code> and <code>cart_checkout_blocks</code> compatibility without any setup.</li>
<li>Cloudflare Image Transformations (CIT) — optional integration to serve via Cloudflare edge (<code>/cdn-cgi/image/format=auto</code>) with automatic availability detection on your zone. If CIT is not enabled on your CF plan, the plugin keeps serving local derivatives without breaking anything.</li>
</ul>
<h4>Free (no license required)</h4>
<ul>
<li>Bulk regenerate with Action Scheduler — async processing resumable after worker death, error classification (<code>oom</code>, <code>missing_original</code>, <code>engine_failed</code>, <code>fs_permission</code>), scope filters (<code>auto</code> = products only based on Settings; <code>all-used</code> = every image referenced in posts/products/Bricks templates/terms).</li>
<li>Embedded sample test — processes 1-5 images on demand and shows the before/after grid with bytes and % savings. Available on the Settings page (“Quick preview”) and on Bulk regenerate (“Generate sample”).</li>
<li>Health page with CDN detection — engine diagnostics, encoders, filesystem permissions, detected competing plugins (Smush/EWWW/ShortPixel/Imagify), Cloudflare Polish status (alerts if active — incompatible with the plugin’s AVIF/WebP), Image Prioritizer (Performance Lab) status with automatic detection.</li>
<li>WP-CLI — 9 commands — 7 free: <code>wp acimg health</code>, <code>stats</code>, <code>regenerate</code>, <code>derivatives <id></code>, <code>purge-cache</code>, <code>restore-originals</code>, <code>migrate-from-sir</code>. 2 Pro: <code>wp acimg doctor</code> (extended diagnostics) and <code>wp acimg reset</code> (full state reset).</li>
</ul>
<h4>Pro (license required)</h4>
<ul>
<li>Cloudflare Image Transformations (CIT) delivery — emits <code><img></code> with CIT URLs (<code>/cdn-cgi/image/format=auto</code>) instead of local derivatives when CIT is enabled on your zone. Defensive automatic fallback to the normal path if CIT is unavailable.</li>
<li>Media Library audit + cleanup — orphan image detector that understands Bricks Builder (PHP serialize), <code>wp_termmeta</code>, WooCommerce shortcodes, custom meta. Trash mode with typed confirmation, immutable audit log, and an <code>untrash</code> endpoint for rollback.</li>
<li>Image Health Monitor — weekly cron that scans for missing derivatives, stale derivatives, Cloudflare Polish conflicts, and storage usage. Email digest to the admin only when there are actionable findings.</li>
<li>AI Alt Text BYOK — alt text generation per attachment via OpenAI Vision (<code>gpt-4o-mini</code>) or Anthropic Vision (<code>claude-haiku-4-5</code>). Bring Your Own Key (no Merchant of Record over AI costs). Context enrichment with WooCommerce product title + category + brand.</li>
<li>Catalog Watch + Auto-Heal — daily cron that detects ghost derivatives (DB rows without files), orphan files (files without DB rows), products with broken thumbnails. Auto-heal with dry-run preview + strict path validation. Persistent admin notice when there are actionable issues.</li>
<li>Multi-Site Manager (Agency) — centralized dashboard to monitor up to 25 client sites from a single wp-admin. BYO Application Password, aggregated metrics (derivatives + bytes + issues), automatic hourly sync + ad-hoc. No external services: direct wp-admin ↔ wp-admin communication via native REST.</li>
<li>CIT Cost Analyzer — daily pull from Cloudflare GraphQL Analytics API. MTD cost + monthly projection + peak day to identify spikes. BYO API token (CF authenticates directly).</li>
</ul>
<h4>Integration with other plugins</h4>
<ul>
<li>Image Prioritizer / Performance Lab — Australcode Uniform Images detects <code>fetchpriority="high"</code> and propagates correct loading/decoding to the final <code><picture></code>. Native LCP optimization.</li>
<li>Bricks Builder — supports <code>wp_get_attachment_image</code> and optional output buffer rewriter for themes/page builders that bypass that filter.</li>
<li>WP Rocket / a3 Lazy Load — compatible with <code>data-src</code>/<code>data-sizes</code> lazy loaders (reads both if present).</li>
</ul>
<h4>v1.0 non-goals</h4>
<ul>
<li>Smart crop — would break the “no cropping” promise. If you need that, this plugin is not for you.</li>
<li>SaaS-only / phone home — the plugin is 100% local. All optimization happens on your own server.</li>
<li>JPEG XL — format still immature in browsers. We will reevaluate in 2027.</li>
</ul>
<h4>How it compares</h4>
 Concern 
 Smush / ShortPixel / Imagify 
 Australcode Uniform Images
 Product photo cropping 
 Smart crop (algorithm guesses) 
 None — pads to a uniform canvas, full product always visible
 Modern formats 
 WebP / AVIF (Pro/paid tiers) 
 AVIF + WebP + JPEG via <code><picture></code> element
 Free bulk limit 
 Capped (e.g. 150 images on the leading “same size” plugin; monthly credit quotas on optimizers) 
 Unlimited — regenerate your whole catalog on Free
 Free formats 
 WebP/AVIF behind paid tiers 
 AVIF + WebP + JPEG, all free
 Page cache 
 <code>Vary: Accept</code> (breaks LiteSpeed, WP Rocket, Cloudflare APO) 
 <code><picture></code> element (cache-safe by design)
 Pricing model 
 $5-15/month SaaS subscription 
 Annual or lifetime license, no SaaS dependency
 WooCommerce-specific 
 Generic optimizer 
 Built for product grids — reads <code>wp_get_registered_image_subsizes()</code>, respects WC thumbnail_cropping setting
 Processing location 
 SaaS server (your images leave) 
 100% local on your server
The other plugins optimize any image. Australcode Uniform Images does one job extremely well: uniform product thumbnails for WooCommerce grids, served cache-safe. If you already have one of the big plugins active, you can run Australcode side-by-side — it only touches images on registered WooCommerce sizes.
<h3>External services</h3>
This plugin connects to external services only when you explicitly enable or 
use the corresponding optional feature. The free, core functionality (uniform 
images, AVIF/WebP/JPEG <code><picture></code>, bulk regenerate, health) runs 100% on your 
own server and contacts no external service.
<h4>Freemius (account, licensing & secure checkout)</h4>
Australcode uses Freemius as its billing and licensing platform (Freemius is the 
Merchant of Record for Pro purchases). Connecting to Freemius is optional: on 
activation you can click “Skip” and the plugin stays fully functional without 
ever contacting Freemius.
<ul>
<li>If you opt in (free or Pro), the plugin sends your admin email, site 
URL and basic environment data (WordPress, PHP and plugin versions) to the 
Freemius API (host <code>api.freemius.com</code>, path <code>/v1/</code>) to create your account and 
check for updates.</li>
<li>If you activate a Pro license, the plugin sends your license key and 
site domain to Freemius to validate the license and enforce the per-plan 
site limit. The license is re-validated periodically.</li>
<li>Purchases and license management happen on Freemius-hosted pages 
(hosts <code>freemius.com</code>, <code>users.freemius.com</code>).</li>
</ul>
No data is sent to Freemius if you skip the opt-in and do not enter a license key.

<li>Terms of Service: https://freemius.com/terms/</li>
<li>Privacy Policy: https://freemius.com/privacy/</li>
</ul>
<h4>OpenAI / Anthropic (AI Alt Text — Pro, Bring Your Own Key)</h4>
If you enable AI Alt Text and provide your own API key, the plugin sends the 
image (as a base64 data URI) plus the related WooCommerce product context 
(title, category, brand) to the provider you choose, to generate alt text:
<ul>
<li>OpenAI Vision (<code>gpt-4o-mini</code>) — host <code>api.openai.com</code>, path <code>/v1/chat/completions</code>
<ul>
<li>Terms: https://openai.com/policies/terms-of-use</li>
<li>Privacy: https://openai.com/policies/privacy-policy</li>
</ul>
</li>
<li>Anthropic Vision (<code>claude-haiku-4-5</code>) — host <code>api.anthropic.com</code>, path <code>/v1/messages</code>
<ul>
<li>Terms: https://www.anthropic.com/legal/consumer-terms</li>
<li>Privacy: https://www.anthropic.com/legal/privacy</li>
</ul>
</li>
</ul>
This runs only when you trigger alt text generation and only with the key you 
supply. The plugin is not a Merchant of Record for these AI costs (BYOK).
<h4>Cloudflare (Image Transformations + Cost Analyzer — Pro)</h4>
If you enable Cloudflare Image Transformations (CIT), image URLs of your own 
site are served through Cloudflare’s edge (<code>/cdn-cgi/image/...</code>) so Cloudflare can 
transform them on-demand. If you enable the CIT Cost Analyzer, the plugin 
queries the Cloudflare GraphQL Analytics API 
(host <code>api.cloudflare.com</code>, path <code>/client/v4/graphql</code>) with the API token you provide 
and your zone identifier, to report usage and cost. The plugin also performs a 
 HEAD request to one of your own derivative URLs to detect whether CIT and 
Cloudflare Polish are active on your zone (no third-party data is sent in that 
detection).
