for doing this.

Using the mouse, click and hold down on the arrow in the small
box, and scroll down to Applications and Directories, and then release.
Under the Directories section, click on Browse and select the directory
you wish to download everything to. For Macintosh computers, we
suggest the Desktop Folder. For IBM PC's, we suggest c:\temp.
Click OK. From now on, anything you download will go to this directory.
to view certain types of files on the Internet (movies, sound files,
pict graphics, etc.), you must configure your Netscape browser to
use certain other helper applications. Below are links to various

type of file served to you from a WWW site has an associated "mime
type" consisting of two names separated by a slash. For instance,
the mime type for a GIF file is image/gif; and for an mpeg movie,
it is video/mpeg. GIF files and JPEG files can both be viewed without
extra software. Netscape has built-in support for them. Here is
a list of mime types for the applications above:
- application/octet-stream and image/tiff.
- same as for NIH Image.
- video/mpeg and video/quicktime.
Machine - audio/basic, audio/aiff, and audio/x-wav.
to set up these mime types, scroll through the list and highlight
the one you want to change, click on browse, and find the application
on your hard drive. When you find the application, double click
on it, and the title under the Application heading should change.
Then simply click on Launch Application to tell Netscape you want
it to use the new application.

click OK when you are done.

FTP, or File Transfer Protocol, is a way of transferring text
and binary (program) files from one site on the Internet to another.
Netscape has built-in support for the FTP protocol, and therefore
no other applications are needed to retrieve files from sites on
the 'Net. To open a FTP session, follow these directions:
the File menu choose Open Location
the dialog box, type ftp://the.site.name, where
the.site.name is the site you wish to connect
to. Press Enter, and Netscape should try to log into the FTP site.

busy place and many sites have limits on the number of people

being over the maximum limit, just click on Reload to keep trying.

structure by clicking on the blue text. Directories will have
a small folder icon beside them and will say Directory in the
far right column. Anything else is a file you can download. To
download a file, simply click on the blue text, and Netscape will

Image. For the Macintosh, we recommend NIH Image. The price
is right (free), it is immediately available via online download,
and it is frequently upgraded. It allows you to conduct measurements
such as length, area, density slicing, profiling, and histograms.
It also allows processing such as stretching, filtering, animating,
and false coloring. NIH Image also allows you to load digital data
sets and build three-dimensional topographic representations.
