Thread:Extension talk:DumpHTML/Error: Unable to copy file/reply (4)

Actually i'm trying this on linux and it is NOT working. I'm using the command below:

php /usr/local/mediawiki-1.18.2/extensions/wikimedia-mediawiki-extensions-DumpHTML-dd18651/dumpHTML.php -d /home/mtz/HTMLDump --image-snapshot --force-copy --group=mygroup

The images are NOT copied. Everything else works except for that though. Interestingly, when I tried testing the script with a new mediawiki installation it works (images and all). Maybe the script works only for small wiki installations?
