I recently inherited web authoring responsibility for a popular sports club web
site. Years ago I was involved in web authoring, but we didn't have this level
of sophisticated software way back then! (it was nearly all done in HTML!)

Some of the images on the index page are probably created as png files in
Fireworks. When I load the image file into Fireworks I can see that it is a
Layer containing individual objects.

My query is - how can I change the individual objects within this layer as I
want to change the photographs the objects (which are bitmaps) represent?
