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 _______________________________________________ MediaWiki-l mailing list To unsubscribe, go to: https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
