SYMPTOMS
When you attempt to view graphics files in Thumbnail view or in Preview mode when you are viewing a folder as a Web page, certain Joint Photographic Experts Group (JPEG, or .jpg) files may not generate an image. However, these files do open correctly when you double-click them.



CAUSE
Typically, .jpg files are encoded in a three-channel, RGB format. It is possible, in some programs, to create .jpg files that are encoded in four- channel, CMYK color format. Windows is unable to display .jpg files that are not in three-channel, RGB color format.
