Here's an overview of the basics of image resolution. Although every digital camera's settings and functions will vary, all brands and camera models follow a single system.
Let's use my consumer grade camera as an example:
I recently purchased an Olympus VR-340, which included a 4GB memory card. At the moment, my camera contains 281 captures (individual photos) that I previously took. After reviewing my camera's function settings, the highest pixel resolution available is a 4608x3456 format at a 16 megapixel weight. The lowest pixel resolution is 640x480, which is abbreviated under "VGA." Since my camera does not list the lowest weight in megapixel units, I researched the term "VGA" and discovered it is actually 0.3 megapixels in size.
And while accounting for my existing captures currently stored on my camera, 281 captures with 4GB of memory in total leaves me 246 more photos left to take at the absolute highest resolution (4608x3456). At the lowest resolution (640x480), my camera informs me that I can still take 9999 photos, but I can take far more than ten thousand photos. This means that with 4GB of memory, the lowest resolution will create images will weight so small that my camera cannot tell me the maximum amount of photos remaining.
This information can come in handy! I would rather use a higher resolution when I will eventually print my photos later. That way, I can receive a clear precise image that seems more presentable. The low resolutions can be useful for sending photos by email or even uploading photos to the Web.
No wonder Facebook photos are never great to print!

1st Blog Post
To kick-start this blog for my Digital Photography class, here's a piece of my own photography taken in Italy last summer:
I spent over forty days in southern Italy to discover my family roots. At any time of day, at any given moment, I captured nearly everything with my camera. By the end of my journey, I had taken over two thousand photos.
