Linda's How-Do-I Series? What's The Difference Between All Those Picture File Types?

Sometimes having a small craft business on the Internet and using graphics or picture enhancing software can be so confusing. Some picture file types are acceptable - other's are not. How is someone to know? And, why is that?

Well, it all comes down to the file extensions.

What is a File Extension?

Well, a file extension is nothing more than the last characters after the period in the name of a file.

For an a more detailed explanation and history of file extension please visit Wikipedia - The FREE Encyclopedia at http://en.wikipedia.org/wiki/Filename_extension . And, for their detailed list of all the file formats and extensions please visit http://en.wikipedia.org/wiki/List_of_file_formats .
