savepict *does* save stamped images such as stamped shapes from the shapes 
centre or stamped text, which becomes a graphic after you stamp it. Here's how 
you do it, with text:-
1. open a textbox and write in it
2. snap the textbox
3. drag it away from the stamped text so you can see the text is stamped 
successfully (this part is now a graphic).
4. cut out the textbox with scissors
5. save it using savepict

The way to get your buttons and animated turtles working on a *.pic file is to 
use the newturtle and newbutton commands to create these features after the pic 
file is loaded. I had a go at this after reading your post. Here's a simple 
example:-

Open a new page, create a button, call it slideshow. Cut out the turtle. Save 
some graphic pages in the same directory, using the savepict command. This part 
was explained really clearly by Wendy Petti in a recent post to this list_serv. 
Thanks Wendy.

to slideshow
loadpict "build1
wait 20
loadpict "build2
vehicle
wait 20
loadpict "greeks
wait 20
end

Slideshow loads the graphics for 2 seconds, moves onto the next graphic etc. 
amongst this I have inserted a vehicle procedure to put an animation onto one 
of the background pictures.

to vehicle
newturtle "car
setsh "car st      ;hatch newturtle, showit, set it to car shape
setpos [-101 -127] seth 90    ; set the position and heading of car
glide 100 1                   ; car moves
remove               ; have to remove it so we can run again next time.
end

The same sort of thing could be done with buttons too I believe.
