Thumbnail View Does Not Work for Certain .jpg Files

ID: Q191811

The information in this article applies to:

Microsoft Internet Explorer versions 4.0, 4.01, 5 for Windows 95

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.
