Get External Images →Comparing Smush with External Images? This page breaks down the key differences and similarities so you can find the best fit for your WordPress or WooCommerce store.
Overview of Smush
Smush is the award-winning WordPress image compression plugin from WPMU DEV. It automatically compresses, resizes, and lazy loads images to improve site speed and boost your Google PageSpeed Insights score.
How External Images differs from Smush
All plugins from Super Speedy Plugins share a SQL-first architecture and an uncompromising focus on performance — and External Images is no different. Here is what sets it apart:
Store your images anywhere – a CDN, Amazon S3, a Digital Ocean space or your affiliate feed – and serve them straight through WordPress. Nothing gets downloaded to your server, so imports run faster and your disk stops filling up. Works with any post type and every WooCommerce product type, including variations and galleries.
Rated 4.65 out of 5 across 26 reviews.
- Import products without WordPress downloading or resizing a single image
- Scale to millions of products on low-cost hosting, with no image storage to worry about
- Works with WP All Import, Datafeedr and any tool that can set a custom field
- Cut disk usage and the CPU normally spent generating 20+ thumbnail sizes per image
How to choose between Smush and External Images?
If you're fed up with plugin updates slowing down your site — and wondering whether Smush's developers ever test against stores with large catalogues — it might be time for a change. Every release of External Images is performance-tested against a one-million-product WooCommerce store to guarantee sub-second response times across every page. Migration is more straightforward than you might expect, and a free trial means you can evaluate the difference on your staging server with zero risk.
What do others say about External Images?
Purchased the external images plugin which was superb. Needed some bespoke work so it was compatible with a third party plugin and Dave was only to happy to help and in record time. Very happy.
I'm impressed. I wasn't sure I would be able to accomplish what I needed with my images. I'm hosting images on my site for SEO purposes. On product upload, I don't need WP to download those images and create multiple versions that a browser could serve (more images served = slower website load). Since I've optimized my images I want WordPress to use those images. With the external images plugin, I'm able to upload my images via FTP. Then I upload a reference to those images in the product upload file. Also, support is fantastic. My theme had a slight issue with external images. Dave personally looked into it and was able to quickly resolve the issue for me.
External Images allowed me to import products at 6x the speed! Great plugin as are Dave's other plugins, and fantastic support. He will make updates to the plugin within days to fix any issues you may run into. 5/5, highly recommend.

What's new in External Images?
3.35 (26th May 2026)
- Added new postmeta filter to add front-end gallery compatibility to latest Houzez theme – they no longer use metabox for their metadata
3.34 (20th May 2026)
- Updated the Super Speedy Settings page: added a "Recheck Licenses" button above the licence table so customers have a clear way to refresh licence status after a renewal or upgrade without scrolling down to the licence-key field. The button is disabled until a licence key is entered/saved and re-enables as you type.
- The Recheck flow now also force-bypasses the auth-server's own 1-hour licence cache (via a `force=1` flag on the `wpiapi/check_product_key` call), so renewals/upgrades that completed less than an hour before a recheck no longer show as expired/exceeded. Normal admin page loads continue to use both caches as before — only an explicit Recheck click bypasses them. (Lives in the `super-speedy-settings` submodule, so the change propagates to every Super Speedy plugin.)
3.33 (18th November 2025)
- Added full namespacing for plugin update checker to prevent conflicts with 3rd party plugins
3.32 (27th May 2025)
- Removed code for checking for and deleting orphans – this can be handled through a KB article instead as it's a one-off job to clean up data
