This is a revised video that includes a section I recorded at a Starbucks, hence all the background noise...

Basically we discovered that Wikispaces exporter does this annoying thing where the image URLs point to the root-level folder...

Example)  <img src = "/mainSpace/files/XXXXX.jpg" />  The leading slash is going to cause D2L to look in the wrong place for the image files!

To fix this, I unzipped the Wikisite on my local machine and used a freeware utility called Tex-FinderX (see link above) to do a find-replace on the text "/mainSource/files/" and replace with "files/" which will look for the image files in a folder called "files" in the same directory as the HTML files, which is where Wikispaces actually puts them.  I'm not sure whether the folder name mainSource will be the same for everyone, but the video shows how to pull up the HTML in a text editor so you can discover what the broken image URLs are and replace them with the correct path.  In the end, the image tags should all look like this:

<img src = "files/XXXXX.jpg" />  where XXXXX.jpg will be the name of the image file.   NOTE THAT THERE IS NO LEADING SLASH before the files directory!  This is called a relative link.

As long as the files folder is in the same folder as the html file, this link will always work!
