Details
[edit]checkImages.php file is a maintenance script to check images to see if they exist, are readable, etc.
Technical details
[edit]These notes based on an examination of checkImages.php from MediaWiki version 1.19.
When executed, the main loop iterates through the wiki database's image table, fetching 1000 rows at a time by default, until all rows are obtained.
Each row specifies an image name, image size, and location of the associated image data.
If the location is filename on a local path, the filename is tested with stat().
| unable to open file | "$IMG missing" |
| file is directory | "$IMG is a directory" |
| image size non-zero and file has zero length | "$IMG truncated ..." |
| image size and file length not equal | "$IMG size mismatch" |
This test does not attempt to read any data from the image files, so it will not detect unreadable blocks in the local file system.
Options/Arguments
[edit]This script does not take any arguments.

php maintenance/scriptName.php instead of php maintenance/run.php scriptName.
