Free software packages I have found useful for digital cameras.
Irfan View -- a totally
free picture viewer program, with a "safe" JPEG rotation feature and
slide show generator. Can also be used to resize, crop, and do
brightness and contrast adjustments. Be sure to also download and
install the "plug-ins" for full functionality. Thanks to Irfan Skiljan for
a fine product with continual upgrades.
Some comments on Batch Scanning, Archival
Image Quality, and IrfanView tips.
Photo Paper Saver -- a picture printer, allows combining of multiple pictures onto a single page of that expensive photo paper. Totally free for laying out one or two pages at a time, the paid version allows more pages for high volume production mode. Some comments on printing pictures.
New version of DRC 12/05/2007
Digital Recorder and Camera program -- an aid to transferring pictures from your digital voice recorder, camera, a flash memory card from such a device via a card reader, or from a Digital Wallet® or MindStor® device. (Digital Wallet and MindStor are registered trademarks of Minds@Work.) Includes renaming pictures to their internal timestamp, and has options for batch resizing pictures and batch converting picture formats. See Organizing Pictures below.
Rename Many -- an aid to renaming large number of picture files (or other files) with powerful control features, it also comes with some sample commands to do common operations that are useful for digital pictures. This has a few more capabilities than the rename features in the current version of DRC, above, but is not packaged as nicely.
jhead -- EXIF data manipulation. Includes ability to remove the low-quality EXIF thumbnail, and can extract and modify EXIF data and rename files. Limited to .jpg file manipulation.
Not free but sometimes worth it

Corel also offers a variety of competitive digital imaging products.
