In ACDSee, for example, go to the File viewer and select the folder you want to work with. In the thumbnails view, drag the images in the order you want them to be in; then select them all and use the Batch Rename function (under the Edit menu). The files will be renamed using the thumbnail display order.
Q) I recently took some pictures at a gathering where I ended up getting red-eye in the images. A friend took shots from the same place I was standing and his images didn't have the problem. Why? P.S. I'm getting good at removing red-eye with Photoshop.
A) Let's clear up a common misconception about red-eye. It's caused by the reflection of light (typically from a flash) off the retina of a subject's eye in dark conditions. Contrary to popular belief, it's not red because of the blood vessels in the eye. Anyone who has taken a picture of a cat at night might have noticed that they didn't get red-eye; they might have gotten yellow-eye. As far as I know, cats don't have yellow blood. While it's true the blood vessels in the eye are red, it's a red pigment layer just underneath the transparent nerve cells that causes the reflected light to be red. Cats and birds have a yellow pigment layer.
Back to your original question. Red-eye can be minimized in a few ways. You can use the red-eye reduction feature on your camera, which causes the camera to turn on a light or fire a series of "preflashes" before the picture is taken. The light or preflashes will cause your subject's iris to close down so that less light enters the eye and is reflected back from the camera. This can be distracting to a subject, however.
