Here's what the website says:
Vector graphics must be supplied as valid Encapsulated PostScript files
(EPS or.eps). A valid EPS file allows all objects within the image to be
edited. Note that anchors are defined points along a line (there
are no lines in raster art). The boundary (or bounding box) is a
temporary border created by the Adobe Illustrator software to allow for
sizing, editing, and manipulation (there are no boundaries in raster art).
Advantages:
File size is smaller than raster/bitmapped images is some cases, but not
all. This allows for shorter loading times for files on the Web.
Images can have unlimited resolution (number of
dots in an image): the higher the resolution, the more clear the image.
This is because vector images are created by math, which
does not have a fixed resolution. The resolution
is affected by the quality of the printer or monitor settings.
Editing can be made easily with a graphics
software, e.g., Adobe Illustrator.
Within the image, each element (line, curve,
box, label, etc.) can be edited separately.
Files can be resized without any loss of
quality.
It seems as though they want the ability to re-size the graphics that you
give them. I'm not totall sure though!
thanks,
