Notes

A GIF (Graphics Interchange Format) file is a 256 color image ideal for line-work to be placed on the web.  GIFs are saved  here with a transparent background.  The bounding box which appears onscreen will not appear on the  web.

An EPS (Encapsulated PostScript) file is a vector-based, high-resolution file that can be enlarged or reduced without losing detail. This is the standard file format for printing. Opening an EPS requires special software, so you may not be able to view it onscreen. If you can view it, it may not look good onscreen but it will print well.

A JPEG (Joint Photographic Experts Group) is a full color compressed image file.  It is ideal for photographs to be placed on the web.  A JPEG is a much smaller resolution file than an EPS and cannot be enlarged without losing design detail. Even though a JPEG file looks good onscreen, it may not print well.
