flash actionscript: Can this effect be done with pure Actionscript or are they using masks and timeline animations?

You would need to use masks, but you could certainly do it with masks created
and assigned via actionscript. I don't really know how you'd do the photo
transitions WITHOUT actionscript, each one depends on the dimensions of the
others at any given time.

Minimum/maximum/desired dimensions, movieclips, masks, and resizing math.

This is what I was thinking of .. although its not quite the same (uses one
image only, and scales parts of it)

you could search the forum archives, we have been discussing that many
times.

I've done this one (in SWISHmax), although only text based .. it is similar

and this one done with images (only a single row, not two rows as your shows
... similar technique though, and also done in SWiSHmax)

I can provide the SWiSHmax actionscript .. would be easily ported to Flash
(script language is almost identical)

It would HAVE to be done with script .. its non-trivial but not really too
complex to do. Urami has a nice example of this sort of thing, I've also
put up an example of it I think. That is assuming you're talking about the
way the pictures expand as you roll over then and shrink as your roll off,
but all of them keep within the rectangle area.
