File Type Descriptions
General
File Types
The following file types are available for
multiple operating systems. The
EPS file format is the sharpest
file format available and is stays sharp
when resized. EPS requires software such
as Adobe Illustrator or Macromedia's Freehand.
If you have EPS based software and plan
to resize or edit the image, EPS is the
recommended method of download.
Note
regarding .eps files in Internet Explorer
for PCs:
When attempting to download .eps files,
Internet Explorer will automatically
change the ".eps" file extension
to ".ps". To ensure the
integrity of the file, please change
the file extension back to ".eps"
when downloading. Be certain to open
the file using an image-editing program.
Simply double-clicking the saved item
in your hard drive will not create
a proper file association, and the
file will not open.

The GIF
file format is used extensively for World
Wide Web graphics. GIF's, unlike JPG's,
support transparency, so using this file
format allows you to insert the graphic
onto a web page in a more seamless design.
The JPEG
file format is used extensively for World
Wide Web graphics. The JPG file format is
a "lossy" format. That means each
time the JPG image is opened, manipulated
in any way and then resaved, the image's
quality will degrade.
The TIF
file format was created for photographs,
but unlike JPG does not lose information
or introduce noise when resaving the image.
The TIF file format works well with page
layout software such as Quark XPress, Adobe
Pagemaker, and Corel Draw.
Windows
File Formats
The following file types are available for
users with the various flavors of the Microsoft
Windows operating system.
The
BMP file format is the Windows
default image file format. Default software
such as 'Paint' can read BMP files easily.
The BMP format is similar to the GIF format
above.
Macintosh
File Formats
These file types are available for Macintosh
users.
The PICT
file format is the Macintosh default image
file format. Default software such as Scrapbook
and the latest versions of Photoshop and
Quicktime can read the PICT format easily.
