Altering Object Properties
Timelines can modify the
width
, height
,
top
, left
,
z-index
, and visibility
attributes of layers, but width and height changes work in
Internet Explorer only (they are ignored
by NN4 and Opera). Timelines can also modify the
src
attribute of
images to create a slideshow. To change
other image attributes, such as to animate its position, place the
image within a layer (likewise for other HTML elements) and then
alter the layer attributes.

Select a keyframe before modifying an object’s properties. You can modify one or more properties at each keyframe using the Property inspector (or by moving or resizing a layer in the Document window).
Table 17-1 explains how to set the attributes of
layers and images. The src
attribute applies to
images only; the remaining properties apply to layers only.
