#1 Information on the HTML Image mapping in general. Using a straight up JPG file.TIF images are not standard for the browser, so GIF or JPG are the way to go. If the images are simple, then just use GIF. If they're pretty elaborate, use JPG.
#2 Information on Leadtools image mapping so the events can be trapped on a TIF image to check the area to see if it is a click to an employee area.Not sure what you mean by "click to an employee area". Do you mean that the user that is viewing the image on the browser can click on the image and have some info pop up (e.g. who's office, their name, title, etc...). Not familiar with the tool, so I'm not of much help in any case.
#3 How to create a way to check the X and Y coordinates of each office/cube so that a Data Entry clerk can enter it easily without getting confused.The end result should be a table that has the squared coordinates for the various parts of the images. This would then be pushed into the html as coordinates for the javascript mouse over and/or click events.
As for how to chop up the image for the purpose of data entry, I'm not sure if there's any tools. Perhaps some VB program that does the chore is in order?
