Check the image exceptions: Tools > Options > Content: Load Images: Exceptions - See Options window - Content panel A way to see if images are blocked is to click the favicon (Site Identification icon) on the left side of the location bar and click the "More Information" button. This will open the Security tab of the Page Info window (also accessible via Tools > Page Info). Go to the Media tab of that Page Info window. Select the first image and scroll down though the list with the Down arrow. If there is a tick-mark in the box Block Images from... then remove that mark to unblock the images from that domain.
