Main thing to remember about this Multi-file Transloading tool, is the URL for the directory must always end in a slash (/). Example:
http://209.15.122.1/username/directoryname/ NOT http://209.15.122.1/username/directoryname/this.gif
If you are wanting images off of a web page, then you will use the full URL, like this: http://209.15.122.1/username/directoryname/index.html or whatever the file name ends with.
To upload image URL's only, you will need to uncheck the box for this.
Fill in the sub-directory you want the images, being transloaded, moved to, if you wish. Hit Upload. You will get a list back of every image on that page. Go down the list and check the box of which images you want to keep. You will get another list of these images and be able to go and check, to make sure they are there.
It's all very simple! I moved every image I had on my GeoCities site, in about 15 minutes. Thanks to Craig, for these great tools!
