KView is an image viewer for the KDE desktop. You can view graphics of many different formats such as PostScript®, TIFF etc. By saving your files in a different format than the original you can easily convert images to other graphics formats. In addition, KView provides some nice little features for doing simple image processing, like stretching/shrinking, rotation and filtering. You can tile your images directly onto the desktop as a background picture, or arrange them in a little slideshow.
