Some .jpg files do not open in Internet Explorer - when I drag them into explorer, I just see a red "x". (These .jpgs open fine in other applications like Microsoft Photo Editor.) If I open these files in Microsoft Photo Editor and simply just save them again, the files then open in Internet Explorer fine. These .jpgs are being created on a Mac OSX platform using Adobe Photoshop. I need to find out what is causing the "red x" problem, and find out what to do when creating these files in order to avoid the "red x" problem in the first place. Thanks.
