# Troubleshooting

# Image Upload

If you can't upload image, or the server throws exception, please check the steps below:

1. Storage folder permission

Make sure your web-server has both write and read access to the storage folder

2. Link Storage Folder

Make sure you linked the storage folder by using the command below:

Linux, Windows:

php artisan storage:link

Mac OS (Run the command to create the symlink manually (assuming we are in public folder):

cd public

ln -s ../storage/app/public storage

3. Image size is too big

Check your PHP.ini file and increase limits (don't forget to restart web-server after the changes)

upload_max_filesize = 10M
post_max_size = 10M
