I can read your mind, too. I bet you're using a Macintosh.

Anyway. You can drag on one of your images from the webpage in Safari to your Mac's desktop. Then click once on the image on your desktop to select it. Then press Command-I - that brings up the information on that file. Near the top of the window there's a section called More Info that says information about the file (in this case it's an image) so it tells you the device make, model, focal length, etc.

If you double click the image and it opens in Preview and then you hit Command-I you can get even more info.

So on that image I can tell a bunch of things.
-Make and model of your camera
-Date/ Time you took the picture
-Your camera was on auto exposure
-Your flash was set to auto but it didn't fire
-blah blah blah

You probably cropped and/or resized the image. Luckily the program that you're using leaves all of those important information in the image metadata. Some programs strip that info out. The info can be very useful in helping you become a better photographer but it looks like you got the jist of it from the pictures you've posted already.
