Of course I looked at your attachment - where else do you suppose I might have gotten the 6.5in width from. You can also see how many times you document has been viewed. If you think a colour picture printed at approx 100dpi looks fine, that's up to you - it's far below the generally-accepted 300-360dpi for a 6.5*4.75in print.
