Hi John,
Yes. I tried both 775 and 777 already. but neither of them worked.
Thanks, Jingyi

Are your permissions set to writeable on the /yourwiki/images directory. I run mine with it set to 775 recursively.

Hi Greg, Thank you for your response! I tried the suggestions, but still facing
same
problems. Were there any further suggestions?
I already changed the owner to be www-data, set log files and rebuilt images.
I got debug logs like follows: "... FSFileBackend::getFileListInternal() given directory does not exist: '/var/www/HIWeb/dir/wiki/images/3/3e' FSFileBackend::getFileListInternal() given directory does not exist: '/var/www/HIWeb/dir/wiki/images/3/3f' FSFileBackend::getFileListInternal() given directory does not exist: '/var/www/HIWeb/dir/wiki/images/4/40' FSFileBackend::getFileListInternal() given directory does not exist: '/var/www/HIWeb/dir/wiki/images/4/41' FSFileBackend::getFileListInternal() given directory does not exist: '/var/www/HIWeb/dir/wiki/images/4/42' ..."
I think the log is reasonable and tell no more issues.
Btw, what the "preview" means in the last post was: when you open a "File:xxxx.png" page, it should show a preview image directly on the
page.
But I have no preview images and thumbnails currently.
Thanks, Jingyi
---------- My original question ----------
Hi all,
Thanks to some help about my previous thumbnails question: "I uploaded a png image but no thumbnails created in the File page."
I have tried several methods but the thumbnails are still not working. I still face the problems that I have neither thumbnails or preview images
in
'File:' pages.
I have already installed ImageMagick in my Ubuntu. What I have tried was to:
- check wiki/images/thumb/ folder, but only old thumbnails are there.
(Yes, I used to have thumbnails several month ago.) No new ones that I uploaded recently are there. 2. chowe -R root:root wiki/images/ and chmod -R 777 /wiki/images/ 2. change memory consumption by increasing $wgMaxShellMemory to 409600 in LocalSetting.php, but still no thumbnails appears.
So here are my new questions:
- Small images (like 500kb) can sometimes have previews (but no
thumbnails). But large images always no previews. How to fix? 2. I have a strange finding. Some jpg images can show the previews in my home computer but cannot show previews in my office computer. What may cause that? 3. My current MW version is 1.26. And my PHP version is a little bit out
of
date: 5.3.10. May this cause a problem related to previews and
thumbnails?
Looking forward to your further help.
Thank you, Jingyi

Actually, the images directory (and subdirectories) should be owned by
the
web server user (that's *www-data* for Ubuntu)
If you enter the command
ps aux | egrep '(apache|httpd)'
and look at the first column, you'll be able to confirm that your
webserver
is running as www-data
Then you can change ownership on the directory and subdirectories like
so:
sudo chown -R www-data:www-data ./wiki/images
In general, you should setup a debug log file[1] to find out what's going wrong with MediaWiki.
[1] https://www.mediawiki.org/wiki/Manual:How_to_debug# Setting_up_a_debug_log_file
- change memory consumption by increasing $wgMaxShellMemory to 409600
in
LocalSetting.php, but still no thumbnails appears.

I'm not sure what you mean by 'previews'. When you upload a file into MediaWiki via Special:Upload, it simply stores the file on the webserver and generates thumbnails as configured. Those thumbnails get stored in
the
"thumbs" directory on the server. When you go to *Special:ListFiles*
(e.g.
https://freephile.org/wiki/Special:ListFiles), it will show a list of uploaded files, with a thumbnail representation of each file.
Since you are having problems with your file uploads and thumbnail generation, you should probably run the 'rebuildImages' script in the maintenance folder.
cd wiki/maintenance php ./rebuildImages --dry-run php ./rebuildImages --missing
