Fix WordPress Media Library Problem
Fix missing images, broken thumbnails, or a media library that won't display correctly.
The Problem
Images you've already uploaded are missing, showing broken thumbnails, or the media library screen itself won't load properly — separate from upload failures, this is about content that's already on the server not displaying correctly.
About this problem
Media library problems usually come down to a mismatch between what the database thinks exists and what's actually on the server's file system — a migration that didn't bring every image size variant across, a theme change that expects thumbnail sizes that were never generated, or orphaned database entries pointing at files that no longer exist.
It's especially common after moving hosting, restoring from an incomplete backup, or switching themes that use different image dimensions than the ones already generated.
What's Included
- Checking whether missing images exist on the server but aren't registered correctly, or are genuinely gone
- Regenerating missing thumbnail sizes for existing images where the originals still exist
- Cleaning up orphaned media library entries pointing at files that no longer exist
- Fixing file path/URL mismatches after a migration or domain change
What's NOT Included
- Recovering images that were never actually backed up or transferred (if genuinely lost, I'll tell you upfront)
- Bulk image optimisation or format conversion (separate services)
- Restoring an entire site from backup — this is scoped to the media library specifically
How It Works
- Compare the media library database entries against what actually exists in wp-content/uploads to find the mismatch.
- For images that exist but show broken thumbnails, regenerate the missing thumbnail sizes from the original file.
- For database entries pointing at files that genuinely don't exist, clean those up so they stop generating errors.
- Check for a URL or file path mismatch after a migration, and correct it so existing references resolve correctly.
- Spot-check a sample of pages and posts to confirm images now display correctly throughout the site.
In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.
Frequently Asked Questions
- Why are my WordPress images showing as broken after a site migration?
- The file paths or domain stored in the database often don't match the new server's structure or URL, so WordPress is looking for images in the wrong place even though the files were transferred.
- Can I regenerate missing image thumbnails without re-uploading everything?
- Yes, if the original full-size image still exists on the server, the various thumbnail sizes can usually be regenerated from it without needing to re-upload anything.
- Why does my media library show images that don't open or display?
- That usually means the database record still exists but the actual file is missing or at a different path than expected — a mismatch rather than true data loss in most cases.
- Will fixing media library problems affect my existing posts and pages?
- No, this fixes how images referenced by your content display — the posts and pages themselves aren't changed.
- Can a theme change cause media library problems?
- Yes, if a new theme expects different thumbnail dimensions than were generated under the old theme, images can appear incorrectly cropped or need regenerating for the new sizes.
