Image Upload Problems

Most image upload failures in WordPress trace back to a small set of server-side limits and missing components. Work through the checks below in order.

PHP Upload and Post Size Limits

WordPress enforces two PHP settings when accepting an uploaded file. If either is too low, the upload silently fails or returns a generic error.

• upload_max_filesize — the maximum size of a single uploaded file. Recommended value: 32M or higher.
• post_max_size — the maximum size of the entire POST request, which must be larger than upload_max_filesize. Recommended value: 64M or higher.

Edit your php.ini file (or a .htaccess / user.ini override if your host requires it) and set both values:

upload_max_filesize = 32M
post_max_size = 64M

Restart your web server after making changes. If you do not have access to php.ini, contact your hosting provider and ask them to raise these limits.

PHP Memory Limit

Resizing a large image at upload time requires available PHP memory. If WordPress runs out of memory mid-upload, the process terminates and the image is not saved.

• memory_limit — recommended value: 256M or higher.

memory_limit = 256M

FW Real Estate generates multiple thumbnail sizes from each uploaded photo. High-resolution source images need proportionally more memory, so if you accept large photos consider setting this to 512M.

GD Library Not Installed

FW Real Estate uses the PHP GD extension to resize images on upload. If GD is not installed or not enabled, thumbnail generation fails entirely — uploads may appear to succeed but no resized copies are created, or the upload fails with an error.

To check whether GD is available, ask your hosting provider, or create a temporary file containing <?php phpinfo(); ?> and look for a GD section in the output. If GD is absent, ask your host to enable the php-gd package for your PHP version.

wp-content/uploads Folder Permissions

WordPress writes uploaded files to wp-content/uploads/. If the web server process does not have write permission on that directory, every upload will fail.

Correct permissions for the uploads folder and its subdirectories are 755 (owner can write; group and others can read and execute). Files inside should be 644. Set these via your hosting control panel, an FTP client, or the command line:

find wp-content/uploads -type d -exec chmod 755 {} \;
find wp-content/uploads -type f -exec chmod 644 {} \;

Avoid setting permissions to 777. That removes write protection from all users and is a security risk.

Recommended PHP Configuration Summary

• upload_max_filesize — 32M minimum
• post_max_size — 64M minimum (must exceed upload_max_filesize)
• memory_limit — 256M minimum; 512M if you upload high-resolution source images
• GD extension — must be installed and enabled
• wp-content/uploads — directory permissions 755, file permissions 644

After adjusting any of these values, attempt a test upload. If uploads still fail, check the WordPress debug log (wp-content/debug.log) and your server error log for a specific error message that can narrow the cause further.
