All the discussion about file formats for the Atlas graphics has been good,


but one perhaps pertinent technical point is missing:  JPEG is a "lossy"


compression format.  Each time an image is saved in JPEG format a small


amount of information is lost.  If the file is opened and then re-saved


several times, the deterioration becomes apparent.  If the file is to be


edited more than once a master should be saved in TIFF (24-bit color) or GIF


(8-bit color) or any other non-lossy format.



I generate the graphics on my web pages in TIFF format and only save the


final, edited page image in JPEG format.
