Hello Daniel,
I tried the suggestion you put at the end of your post. I have a local wamp install on my laptop where I'm doing the migration. I copied the whole Drupal "sites" folder to my Joomla installation folder and also to the webroot because I saw some images linked to ../sites/(etc). The migration itself is going great! Thanks for that! More than 300 users and 900 articles migrated to Joomla in less than an hour!
The problem is that after parsing the content there are a lot of error messages saying that the image file could not be opened. When I copy-paste the path the error message shows and put that in my browser, the image does show so I don't get why it is not working...
I'm also a bit confused what to put at the "Base site URL:" at "Parsing configuration" setting. I that the base url of the joomla site or the url to the original Drupal site?
I hope you can help me out. There are about 600 images not imported now...
Best regards,
Sijmen
