On a forum I use (its a MYFF forum) when using Firefox, sometimes certain button icons ( edit delete send PM) are not displayed. Instead a link text appears. When I right click on the link text I am offered "view image info" even though I'm not on any visible image. A list appears of images on the page and the url of the image I cannot see is in the list. When I look at the image details, it says that the pixel size is 0px × 0px (scaled to 122px × 15px). M+Note that in Internet Exlorer ther is no problem, the image is displayed.
