Thread:Project:Support desk/Pictures don't show after importing xml-dump/reply

I think importImages.php will fail if the images you're trying to import are already on the correct place where MediaWiki would store them, because the script will try to copy them on that location, and if the file already exists, I imagine it will fail somehow.

It may also be a cache problem, if the files were imported successfully. Try purging one of the pages to see if it displays the file properly.
