As of this morning I am unable to view images in Internet Explorer 7 using the viewer. The progress bar for the download shows a little green then nothing else ever happens.
However I was able to go back to the old viewer and for the moment I can view images in Internet Explorer 7.
Here's how I did it:
1. Select the Internet Explorer Tools Menu
2. Select Manage Add-Ons
3. Select Enable or Disable Add-Ons
4. Disable the add-on with the name "Image Control Class",
the publisher is the ever popular "My Family.Com Inc."
5. Restart Internet Explorer.
Note: The default view for Mange Add-Ons is "Add-ons currently loaded in Internet Explorer". If you ever want to restore the Enhanced Image Viewer without downloading it again, you will need to change the view (Show:) to "Add-ons that have been used by Internet Explorer".
