You may have accidentally clicked the 'Block Images' item in the right click context menu while trying to save an image. Check the image exceptions: Tools > Options > Content: Load Images: Exceptions - See: Options window - Content panel

A way to see which images are blocked is to click the Site Identification icon (favicon/image on the left end of the location bar) and click the "More Information" button. -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 an image in the list is grayed and there is a check mark in the box "Block Images from..." then remove the check mark to unblock the images from that domain.
