When you use Windows Photo Gallery to view TIFF images that do not fit into one page in Windows Vista, the system performance is slow.
To determine the file type of an image, go to the "" section.
Immediately after the first in a series of images has finished displaying on the screen, Windows Photo Gallery loads the next image. This process is also known as precaching. If the next image is a multipage TIFF file, Windows Photo Gallery processes the complete file. This process may take a while and use too many system resources, depending on the size of the TIFF file. This behavior causes slow system performance and a significant increase in the memory usage of the computer.
How to determine the file type of an image
To determine the type of the image file, use one of the following methods:
Right-click the image file, and then click Properties. In the General tab, you can find Type of file.
Uncheck the "Hide extensions for known file types" option in the View tab after you double click Folder Options in the Control Panel. This displays the file type of all files.
