There's a couple other ways I routinely use when examining photos, too. If the photo has been uploaded to Flickr or Photobucket, both sites will give you the EXIF data, though Flickr calls it Properties and Photobucket calls it Image Info.
If you have Adobe Lightroom, it will also show the EXIF data, even for photos that have been emailed to you or downloaded.
All of this is assuming the EXIF data hasn't been deliberately stripped or faked, though....

I use EXIF data constantly to figure out why a photo did or didn't turn out right, especially when taking night photographs. This data can tell us nearly everything we need to know from the camera model that was used down to the individual settings. Settings are useful, of course, for determing the causes of anomilies. Or, just as importantly, what was not the cause, meaning a blur wouldn't be likely when the settings were very quick. The camera model is useful in determining the quality of optics - many camera models are prone to "artifacts" - and in determining the capabilities of the camera to help improve the pictures.
Many common programs have EXIF viewers with plugins to ie, firefox, and explorer, but to make things easier I'll just link a free viewer I use. It's called EXIF Pilot Light (windows 98/xp/vista) and can be safely downloaded here. The perks include full exif data instead of just the basics, a thumbnail viewer, and the ability to click the photo and preview the full version in windows explorer. The only thing I don't like is that you can't copy the exif data... boo. But it's better than the photoshop viewer.

Pretty basic. Directories on the left. Find where your photo is. Click it, you get a thumbnail. The default is the basic file information on the right. See the EXIF button under the thumbnail? There's the good stuff, click that.
The camera settings are too complex to even begin with, maybe some of the others would like to get started on that but I'm not that motivated yet. Either way, here is a great beginner's tutorial.
I'm only scratching the surface here, would love to hear more input!

I have experienced many paranormal events since I was a child. being aware of the spirit world, I noticed something else.
when there is a haunted location, there also is animals that just come and go at random. as if they are drawn there by the
unseen. I am not talking about animals showing up once or twice, but many times, weekly, dogs, cats, and they stay for a minute
and then they are on there way only to be exchanged for other animals. not ghost animals, real animals, coming from
seemingly nowhere, and leaving just the same. this happens many times over short periods of time and it is constant.
whatch for this conclusive sign. animals are drawn to hauntings. something to think about if you suspect paranormal
activity.

As requested, here is a bit of information to help in understanding EXIF (exchange image file format) in digital photos. Keep in mind this is only helpful in photos taken directly from digital cameras. Scanned photos do have EXIF meta data but it doesn't display this information. EXIF data can now be edited pretty simply, so it's not a sure fire way to tell if a photo is genuine, but it can help guide us in finding out why a photograph may look the way it does.

In response to that I'd like to say that I finally downloaded a free program as well. After searching, I chose Opanda IExif 2.3...didn't know about the one you use. In any event, I did it to prove a point when someone on another paranormal site critiqued a photo that I had sent for analysis. The guy was so obviously bent out of joint and accused me of fakery, Photoshop or taking a "photo of a photo on my computer screen" to reproduce an obvious "orb" hanging over two subjects in two of my photos. Consequently, I haven't visited that site since, but another person actually used his intelligence and provided the EXIF data on my photo and confirmed it had never been Photoshopped, manipulated, edited or anything like that. Although I "won" that round, I decided to download my own tool, even though I don't understand it. It's now available for anyone who might question the authenticity of a suspected paranormal photo; the tool reveals all and it's good to have as a backup for skeptics or "idiots" like I encountered on that other website.

http://chdk.wikia.com/wiki/CHDK I can now shoot raw images, either in canon's *.crw extension or in adobe's *.dng ext. Only the dng raw format gives me exif info. Xnview reads all formats including the exif info fine. But apparently only Adobe can import a dng (read adobe format) file, with exif, and correctly and automatically fix any badpixel data. The chdk firmware only touches the camera's sd card and has numerous fine-tuning features including 3 games, a text viewer, & a simple calendar. I found with my 6 MP ccd elph it would only accept a 2GB card as it refuses to format per sd fat specs beyond that size. There are scripts on chdk which enable remote motion detection camera and video modes but don't work with all canon's. Here is a formatter (card tricks 144) made by the chdk devs which will also take you to the down page: http://chdk.wikia.com/wiki/CardTricks
Here is another interesting free prog called geosetter http://www.geosetter.de/en/ for those who do not have that feature. I tried using it without adding geotag info and prog acted as if the pics were locked or something ? Not sure. I was totally ignoring my elph until I found all the hidden features and am somehwat of a noob when it comes to taking pics. Raw Therapee http://www.rawtherapee.com/ will edit exif info. The other progs mentioned do not see raw images and are useless to me.
HP also has a free sd formatter as well: HPUSBFW 2.1.8.0 at http://hp-usb-disk-s...former.com/2.1/
