Hi All, sorry for the ambiguous title but I am not sure of the correct terminology for what I want to do. Basically, my need is to be able to click anywhere on an image (picture or diagram) and be able to open a separate file dependent upon where i have clicked. For example, if the image is a plan photograph of an engineering site, say a waterworks, then I would like to be able to mouse over an area of the site and click to take me on to further information which may be a menu of options or another file.

Having looked through the info I have I guess this may make use of layers but I have been unable to see quite how it would be done. Is it possible, and if so, can someone give me a pointer or two please?

Many thanks,
Trev
