So we thought it would be easier just to show you than to talk a lot about it. Maps: are described as coordinates of areas within a graphic on the page "map" which react to clicks, then deliver an "action" to the browser. Go ahead ... try it. Red Normal Green MAP Text Slice Here is the actual code for the MAP at left above. <MAP Name="Map"> <AREA Shape="Rect" coords = "0,0,107,22" HREF="RResult.html"> <AREA Shape="Rect" coords = "0,23,107,53" HREF="NResult.html"> <AREA Shape="Rect" coords = "0,54,107,82" HREF="GResult.html"> </MAP> You see the area, the coordinates, and the HREF "action" to be taken. This block of code is at the BOTTOM of the html page. (Peek at the source and you'll see.) The image link itself is: <IMG SRC="Map.jpg" BORDER="0" USEMAP="#Map" ISMAP> Note that the tag "USEMAP" has the attributes of an anchor "#Map" which tells the browser to go and find the MAP code (above), then decipher the coordinates, and perform the request. ISMAP tells the browser that this is really a Map and should be handled as such. Slices on the other hand are THREE individual JPG files, carefully cut apart out of the original art so that when put into a table with ZERO attributes (0=border, 0=padding, 0=spacing) they will appear to be a seamless picture. (Peek at that source too and you'll see.) These "Slices" are then linked with traditional html tags. <A HREF="Gresult.html"><IMG SRC="slice3.jpg" WIDTH="108" HEIGHT="29" BORDER="0"></A> __ Generally, a SLICE will take more code, and be more problematic, yet be easier for the coder to build the html for. While MAPS are more streamlined, with less code (and some say load faster) they are much harder to build unless your software program does it for you. Ours does.
