未创建Wordpress图像缩略图

Question

I think this is more than a plugin or install issue, I think it may be a server issue.

Basically when I upload any image, say filename.jpg, the typical filename-150x150.jpg thumbnail version of the image is not being created in my uploads folder beside the original. But there are no upload errors, all goes through fine. But when I need the thumbnail somewhere in the code, it's not finding one (and I don't see it in the uploads folder, although I see the original file there).

I'm on Amazon EC2 (AMI) running your typical Wordpress setup (PHP 5.3.29, MySQL, Apache).

Any ideas on why these thumbnails might not be getting created, or where I could search for any errors happening?

Answer 1

It appears PHP GD wasn't installed.

Ran these two commands:

sudo yum install php-gd
sudo service httpd restart

And then used the Regenerate Thumbnails plugin to regenerate my thumbnails and everything worked.

Thanks to @Quantastical for the help.
