Common Issues For WordPress Not Uploading Images And How to Fix Them
When You Cannot Upload a Particular File
Resize the image to solve image upload issues in WordPress
Rename the image
WordPress can reject images with special characters in their filenames, which may cause upload failures. Image filenames with special characters can cause upload failures. Special characters such as %, &, #, or spaces in image filenames can interfere with how WordPress processes uploads, leading to errors or failed uploads, and in some cases may even result in broken images on your WordPress site. To avoid this, use only letters, numbers, dashes, or underscores in your image filenames.
When you get file size errors
Increase max file size
When you cannot upload (and your media gallery shows blank images, or you recently migrated to another host)
Change file permission for upload folder
Make sure the uploads folder has the right permissions so WordPress can create new folders when needed, and confirm the settings with an FTP client such as FileZilla. Wrong permissions can prevent images from appearing in the wordpress media library even if the transfer starts, which can also affect the website after a migration or server move, especially if you are also using a WordPress cloud storage plugin that mirrors or offloads your media files. In most cases, folders should be set to 755 so the web server can write to them without opening up unnecessary access, and you may want to pair this with WordPress user access control plugins to better manage who can upload or modify media files.
Files inside the uploads directory are typically set to 644, and permission problems can also cause files to go missing from the media library. Avoid using 777 permissions for security reasons.
Getting a WordPress HTTP Error When Uploading Images to WordPress
Increase the memory limit to solve image upload issues in WordPress
Set the image processor to use one thread
WordPress uses either the GD Library or Imagick to process uploaded images, and issues with these libraries can sometimes cause upload errors. Optimizing your media by serving properly scaled images in WordPress can also reduce processing overhead and lower the chances of memory-related upload problems.
Other Solutions for Fixing Image Upload Issues in WordPress
Use the browser uploader
If you get an HTTP error in the wordpress media uploader, open the Media screen from the wordpress dashboard and try the browser uploader when the standard uploader fails, and also rule out general connectivity issues such as the ERR_CONNECTION_REFUSED browser error. It can bypass some HTTP errors by using the browser’s built-in file upload method for a media file, and if the problem persists, it can still be a useful workaround for some image upload issues on a wordpress site.
Clear cache if you are using a caching plugin
If you are using a caching plugin, clear your cache to ensure that outdated files or settings are not causing upload issues. Sometimes, cached data can interfere with the media uploader or prevent new images from appearing in your media library.
Disable Plugins
Temporarily disable your plugins to check for conflicts that may be causing image upload issues, and follow best practices for safely deleting problematic WordPress plugins once you identify one that is no longer needed. Some plugins, especially those related to security or optimization, can interfere with the upload process. If disabling plugins resolves the issue, reactivate them one by one to identify the culprit.
