ACDSee is a very fast, easy to use JPEG/GIF/PNG/etc viewer. Good viewing and browsing capabilities, including a fast preview display; but no image editing or conversion functions. Both Windows 95/NT and Windows 3.1 versions are available from http://www.acdvictoria.com/acd/download.html or ftp.acdsystems.com:/pub/acdsee32/. Shareware, $30. IrfanView is a popular viewer/converter for many formats including JPEG, PNG, and GIF. Requires Windows 95/NT. Current version is 2.83, available from ftp.simtel.net:/pub/simtelnet/win95/graphics/iview283.zip. Free. LView Pro is a viewer/editor/converter for JPEG, GIF, BMP, and other formats. It offers a wide array of image editing functions and can load JPEGs in either fast/low-quality or slow/high-quality modes. Requires 386 or better CPU. The current version, 1.D, runs under Windows 95, Windows NT, or Windows 3.1 with Win32s 32-bit extension. It's available from ftp://ftp.std.com/ftp/vendors/mmedia/lview/. Shareware, $30. An older version that can run under vanilla Windows 3.1 is ftp.simtel.net:/pub/simtelnet/win3/graphics/lviewp1b.zip. ThumbsPlus is an image browser and cataloger that handles many file formats. It can also do some editing and format conversion, but indexing a large image collection is what it's really aimed at. Current version is 3.20, at ftp.cerious.com:/pub/cerious/thmpls32.exe. Shareware, $70. Requires Windows 95 or NT, or Windows 3.1 with Win32s. VuePrint is a widely used viewer and printer for JPEG, GIF, BMP, and other formats. Shareware, $40. Version 7.3 is available from http://www.hamrick.com/. Another good viewer/browser/indexer is CompuPic, available from ftp://ftp.photodex.com/ (Windows 95, NT, or 3.1+Win32s) or ftp://ftp.photodex.com/ (Windows 3.1). Shareware, $40. Many people like Paint Shop Pro. It's overkill as just a JPEG viewer (especially since image quality is not very good on 8-bit displays), but as an image editor and manipulator it is very strong. Current version is 4.1 for Windows 95 and Windows NT 4.0; an older version is still available for Windows 3.1. Available from http://www.jasc.com/. Shareware, $69. WinJPEG displays and converts JPEG, GIF, TIFF, BMP, and other file formats. It has some other nifty features including screen capture, color-balance adjustment, and slideshow. Shareware, $25. The current version is 2.84, available from http://www.pixvision.com/html/downloads.html. WinECJ is a fast, no-frills viewer with image quality noticeably worse than most other JPEG viewers. (You can purchase a version with better image quality for AUD$30.) Version 1.2 is free and available from ftp://ftp.coast.net/coast/win3/graphics/. QPV and DVPEG (see previous section) work under Windows, but only in full-screen mode, not in a window. Also note that you can run the DOS conversion programs described earlier inside a Windows DOS window. JPEG Optimizer is a standalone JPEG compression program that lets you interactively preview the results of different compression settings. It also has both automatic and manual selective-compression ability: parts of the image that have finer detail or are more important can be compressed less heavily than parts with less detail. Shareware, $29. Requires Windows 95 or NT 4.0 or later. Available from http://www.xat.com/. PIE is a utility program designed for digital camera users: it can extract auxiliary information (exposure data, etc) that most digicams include in their JPEG output files. PIE can also do lossless rotation of JPEGs, something that you cannot do with traditional image editors (because loading and resaving in an editor incurs at least roundoff error). Requires Win32. Version 2.8 is available from http://www.snafu.de/~hoju/. Shareware, $19. Photoshop 4.0 supports progressive JPEG. If you have an older version, you can get a plugin that enables progressive JPEG loading and saving from Pegasus, http://www.jpg.com/. The plugin is free for loading, shareware ($29) for saving. Other Windows 95 native releases include: * PolyView. Reads JPEG, PNG, GIF, BMP, Photo-CD. Current version is 3.03, available from ftp.winsite.com:/pub/pc/win95/desktop/polyv303.zip. Shareware, $20. Other popular Windows NT-only viewers include: * PolyView. Reads JPEG, GIF, BMP, Photo-CD. Current version is 1.70, available from ftp.winsite.com:/pub/pc/winnt/misc/polyv170.zip. Shareware, $20. If you're a programmer looking for JPEG support under Windows, consider the free JPEG source code in item 15, or these pre-canned alternatives: TwistedPixel, an OCX component that reads and writes JPEG and other formats (and also does many other kinds of image manipulations), is available at http://home.earthlink.net/~bananasoft/twisted.htm. OCXs are usable by Visual Basic, Delphi, and other non-C programs. Shareware, $69. Requires Windows 95 or NT. ImgDLL is a Win32 DLL that reads and writes JPEG, PNG, TIFF, and BMP files and provides various image processing functions. Shareware, $15. Available from ftp.simtel.net:/pub/simtelnet/win95/dll/imgdll33.zip.
