Well Vanessa ... there are several factors to consider here.

1. Getting a hard copy can be difficult if you want a quality image.
The net currently require 72 dpi (dots per inch) in graphics files.
A photo-realistic printer (Epson or HP for example) often requires
at least 100 dpi to print a sharp image. At 72 dpi you may not have
enough data to print a quality image.

2. Each image in the net has been saved as a particular file type
(Gif, tiff, jpeg for example) and each image was saved at a
particular size measured either in inches, pixels, or cm
(.09X1.42 inches for example) .... and each graphics files was saved
at a specific dpi. Small 72 dpi images cannot be enlarged to large
physical sizes without some blurring.

3. In order to get a decent image you have to pay attention to the
rules of file size and dpi. Choose your files carefully and convert
them through an imaging program (Adobe PhotoShop is my favourite) and
then resize and resave them before printing. If the information has
been built into the file it is possible to get a very nice print many
times larger than the original physical size ... if the dpi is high
enough.

Hope this helps.
