FIV allows you to view a wide range of image files on your Windows device. It is designed to load images quickly and efficiently even on less powerful devices. It can be used by opening a file outside of FIV that has set its default viewer to be FIV or from the file picker within FIV. FIV can be used to view photos, engineering drawings, medical images and more, but its main focus is on viewing images that other viewers find difficult: large bitonal images, multi-page and 'complicated' TIFF files, and legacy formats. It can view photos, well logs, DICOM medical images, FAX files and more. FIV can display detailed EXIF information about photos and show points on a map where the photo was taken. It also supports animated files (GIF, FLI, FLC, DICOM). The following formats are supported: JPEG, TIFF, BMP, PNG, Targa, PBM/PGM/PPM, GIF, PCX, DCX, FAX, DICOM, JEDMICS, CALS, AWD, FLI/FLC, IOCA/MODCA, PDF (limited to images), LaserFICHE, Fortis.
