If speed is not a problem, what about the 2000 pixels? Have the employees
got such big screens?
OK. Lets suppose scrolling is no big deal. You have this big map in a table
all sliced up in a hundred bits. The customer/employees (a captured market
eh?) click on some list you have. Depending on the thing they click, a map
will appear with a particular bit highlighted.
Excuse me if this seems a bit dumb but it is a solution: you have each link
go to a different html page. Each page will be very similar, just one cell
different to a master table (in which no cells are "highlighted" - a table
that you do not necessarily display, it being your working behind-the-scenes
template). How many links are in the list? However many, you will have as
many html pages. It is easy for you to do. Only those are called from the
server that are needed. And, even though speed is not a consideration, it
will also be fast if someone is browsing to see various parts of the map or
offices or whatever because all the images in all the cells will be cached
and appear quickly *the second time* around (at least).
There may be more elegant solutions with javascript and rollovers and stuff.
But by the time you have coded for it all, you might have done the above
which will sure fire work.
I hope this helps.
