You can also try setting the blendLevel property:

repeat with i = 1 to 100
   set the blendLevel of img "myImage" to i
   wait 1 tick
end repeat

You can play with the wait interval to speed it up or slow it down,  
or set the step interval in the repeat loop higher, eg.

repeat with i = 2 to 100 step 2

In 2.7 you can use this technique with any object, including the stack.
