Processing 50,000 Supplier Images Without Timeouts

The Problem: An enterprise dropshipper attempted to upload 50,000 high-resolution supplier images via generic WordPress plugins, repeatedly triggering 504 Gateway Timeouts and exhausting PHP memory.

The Solution: Bypassed the WordPress media uploader entirely by transferring the raw files via secure SFTP and executing a custom WP-CLI script to silently register and attach the images in the background.

The Results: 100% of images attached to WooCommerce SKUs with zero server lag or downtime.
