Smart Auto Upload Images automatically imports external images from your post content into your WordPress media library. When you save or update a post, the plugin detects any external image URLs, downloads them to your server, and replaces the original URLs with your hosted versions. This improves site performance, ensures image availability, and gives you complete control over your content. Why Auto Upload Images to Your Media Library? When you copy content from external sources or use remote images, you risk broken images when the original source removes them. Hosting images on your own server provides several benefits:

Better SEO performance - Search engines favor self-hosted images
Faster page load times - Eliminates external HTTP requests
Full content control - Images remain available even if sources go offline

How Auto Upload Images Works The plugin runs automatically whenever you save or update a post. Here's the process:

Scans post content for external image URLs (any image not hosted on your domain)
Downloads each external image to a temporary location
Validates image file integrity and format
Uploads valid images to your WordPress media library
Replaces original external URLs with new local URLs
Attaches imported images to your post in the media library

No manual intervention required. Just write your content and let the plugin handle the rest. Key Features Automatic External Image Detection The plugin automatically identifies external images in your post content when you save. It distinguishes between local images (already hosted on your site) and external images that need importing. Smart URL Replacement After importing images, the plugin intelligently replaces all instances of the external URL with your new local URL. This works with images in:

Post content (Classic Editor and Gutenberg blocks)
Image galleries
Featured images

Media Library Integration All imported images are added to your WordPress media library with proper metadata. You can:

Edit images using WordPress image editor
View which post each image is attached to
Set custom alt text during import
Apply your site's image optimization settings

Flexible Domain Exclusions Exclude specific domains from auto-import. Useful for:

CDN-hosted images you want to keep external
Partner websites where you have permission to hotlink
Your own secondary domains
Social media embeds you want to keep as external

Custom Post Type Control Choose which post types trigger auto-upload. Enable for:

Posts and pages (default)
WooCommerce products
Custom portfolio post types
Documentation posts
Or disable for specific types you want to skip

Advanced File Naming Patterns Set custom file naming patterns for imported images using dynamic tags:

%filename% - Original filename
%post_title% - Current post title
%post_id% - Post ID
%image_title% - Image title attribute
%date% - Current date
%time% - Current timestamp

Example: %post_title%-%filename% becomes my-blog-post-example-image.jpg Custom Alt Text Patterns Define alt text patterns for better SEO:

%post_title% - Use post title in alt text
%filename% - Use filename as alt text
Custom text - Set consistent alt text across imports

Image Size Constraints Set maximum width and height for imported images to:

Control storage usage
Maintain consistent image sizes
Automatically resize oversized images
Prevent huge images from slowing your site

Featured Image from URL Set a post's featured image using an external URL. The plugin will:

Download the image from the URL
Import it to your media library
Set it as the post's featured image
Work via REST API or post editor

How to Set Featured Image via URL Using the Post Editor: Step 1: Edit your post Step 2: Find the Featured Image section in the sidebar Step 3: Enter the external image URL in the "Set from URL" field Step 4: The image imports automatically and sets as featured image Integration with Page Builders Auto Upload Images works with popular page builders: Gutenberg Block Editor All images in Gutenberg blocks are automatically detected and imported when you save the post.

Custom Post Types Configure any custom post type to trigger auto-import functionality. Just ensure Auto Upload Images is active when running imports. Performance and Storage Considerations Server Storage Imported images consume server storage. Monitor your hosting plan's disk space if importing large quantities of images. Import Speed Import time depends on: * Image file sizes * Your server's download speed * Number of images per post * Configured maximum dimensions Optimization Tips

Set maximum width/height to reduce storage
Use an image optimization plugin after import
Exclude domains hosting very large images
Test with small batches before bulk imports

Developer Features Filter: smart_aui_validate_image_url Programmatically control which image URLs get imported.

php
add_filter( 'smart_aui_validate_image_url', function( $is_valid, $url ) {
// Skip images from specific paths
if ( strpos( $url, '/cdn/avatars/' ) !== false ) {
return false;
}
return $is_valid;
}, 10, 2 );
