Image quality is an issue that is often overlooked.  With the emergence of Web 2.0 and social media, digital imaging has taken over.  There are an abundance of digital photographs made easily available on line.  But, is this an acceptable practice for archiving and maintaining image quality.  Whatever happened to scrap booking?With most digital images distrusted through social networking sites like Facebook, Flikr, and hi5, people seem to be happy enough with just looking at photos on their computer screens.  This works well for that mean but what about if someone were to want to print these images for a card or scrapbook or to put on their refrigerator...  Because bandwidth and storage are issues, social networking sites destroy the printable quality of your photos to optimize for a computer screen viewed at 72 dots per inch (DPI).  Acceptable print quality, conveniently, is 150dpi - 300dpi for magazine like publications and photo printing.  Images from social networking sites are best printed in thumbnail sizes.  Originals should be backed up and saved in their original state, especially if at some point you plan on printing them.
