Hi everyone. I'm looking to purchase a digital camera and know absolutely nothing about them. It seems that price depends on megapixels. Now, her comes a question that really shows my ignorance: What is a megapixel and why does it seem so important. Does it have to do with the quality of picture, and are the lower megapixels really that different? I want so bad to post pictures so I need a little info before I 'Make the leap' . Then after I figure out what to buy and how to use one, you guys (and gals) will have to bear with me and teach me how to actually post pictures.
