No thumbnails preview.

[softyoda]

Hello, i have a problem, i havn't any preview of the picture, and with folder with a folder.jpg, no thumbnails.
I have the last version of Minigal and PHP and all flower are in chmod 775, i also use nginx.

I don't have any flower "thumb".

• Do you have the PHP GD extension installed and enabled?
• Are there any errors in your webserver logs or browser console?

Ok it worked with $ sudo apt-get install php7.0-gd
and $ sudo service nginx restart

Thank you

Thumbnails caching : No : You should let php create and use the 'thumbs" directory. MiniGal will be much faster.

I don't know why it don't save thumbnails in a folder.

• any errors in your webserver logs or browser console?
• The thumbs directory should have read/write/execute permissions for the user or group running the webserver (usually on Debian-based systems it's www-data)

In my browser console, i have this error : TypeError: document.getElementById(...) is null

I did not found any log in my /var/log/nginx/error.log

And i have set all permision to chmod -R 775

The solutioni have find is to set all right to execute, but i prefere desactivate it in the public web, so i generate my tumbs with the right to execute and then, i desactivate after, because i don't want anybody to execute an injection.

@softyoda Having file mode 0775 is not enough, you need to ensure files have proper owner/group as well.

set all right to execute

If this works then you probably have wrong ownership on your files. The preferred way to restrict permissions to the minimum is:

• create the thumbs directory: mkdir /var/www/minigalnano/thumbs
• set minigalnano files/dirs ownership to root:www-data: chown -R /var/www/minigalnano root:www-data
• ensure files are mode 0640 and directories mode 0750:

find /var/www/minigalnano -type f -print0 | xargs -0 chmod -c 640
find /var/www/minigalnano -type d -print0 | xargs -0 chmod -c 750

• give the webserver write access only to required directories: chown -R www-data:www-data /var/www/minigalnano/thumbs
