Thumbnail View Does Not Work for Certain .jpg Files

View products that this article applies to.

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.
