Traditionally, the only types of images that are commonly used as
inlined images are GIFs and xbm bitmaps (this is because these are the
2 types that Mosaic allows --- I don't know much about
Netscape/Mozilla). xbm bitmaps are black and white; GIFs are color.
To put an inlined graphic in a page, you use the HTML:
<img src="URL HERE">
To put in a non-inlined graphic, you use:
<a href="URL HERE">name-of-graphic</a>
(just like as if you were specifying a link to an HTML document)
Ergo, the graphics you mentioned above were probably done like
this:
<a href="URL of large version of graphic"><img src="URL of small
version of graphic">Click on this icon to see a larger version of this
graphic!</a>
Hope this helps.
