Texas A&M graduate student Roman Kogan has written an interesting program that turns your webcam into scanner camera.
This program turns your webcam into a scanner camera, similar to the ones used to record photo finishes, but much, much, much slower. With it, you can create images like the ones on this page with ease and with no digital manipulation! It works by taking one pixel line at a time and arranging those slices in a line to produce the image. Thus one dimension of the image is spacial, and the other is temporal.
If you’re not naturally an organized person, then figuring out where certain photos are on your computer or external hard drive might be a pain. Adebis Photo Sorter [now defunct] is a free Windows program that uses the EXIF data in image files to automatically rename and/or organize your image files in a new directory, leaving the originals untouched. It supports pretty much all the popular image formats, from JPEG to Raw image formats, and can even help you include EXIF data in the new filenames.
Photo Magician is a free and lightweight (less than 1MB) program for Windows that allows you to batch convert a directory of photographs. It’s similar in functionality to Photoshop’s “Image Processor” feature, with one difference being you can’t select the output quality like you can using Photoshop.
The program also features a “Quick Convert Mode”, which minimizes the program to a little box onto which you can drag and drop folders of images. If you’ve been looking for a quick way to resize images in Vista (like the Image Resize PowerToy allowed you to do in XP), then you might want to check out this program.

P.S. For a more powerful free program that’s even more similar to Photoshop’s Image Processor, you can check out BIMP Lite.
A few times in the past I’ve had to recover data from memory cards. Once it was a friend who accidentally reformatted the card and deleted hundreds of photographs from a recent vacation. Another time I accidentally deleted precious images from the memory card before I had backed them up. What I’ve learned though, is that in most cases, you can easily recover the data you fear was lost, even if you do something drastic such as reformat your card.
When you “delete” a photo from your memory card, it simply goes to that section of storage and marks it as “available” to be used again. The data of the original image is still there on your memory card, though the camera will not display it as an image. Thus, the most important thing you need to remember to do if you accidentally delete data is to stop using the memory card. This is because the only way for the data to truly become unrecoverable is if you delete it, then overwrite it with new data (or even blank data). Thus, to ensure that you can recover your deleted photo, you need to be sure to stop using your card immediately to ensure that nothing is written to that storage location on the card.
To do the actual recovery, you could take the card to a photography place and have a professional recover the data for you, but I’ve always relied on free software that can do the same thing. Here are some popular and free programs to try:
Most of the good, safe, and free programs available for recovering photos are available only for Windows users. PhotoRescue is a popular program for Mac users, but costs $29.
Finally, the fact that data is so easily recoverable means that you need to be careful when selling things like computers and memory cards. Simply “deleting” data will not prevent what was on the card to fall into the wrong hands. If you’re selling a memory card that contained data you don’t want others to possibly recover, then be sure to overwrite the card completely, or look online for a program that helps you safely delete data.
