I want to use the classic warp effect of grow and shrink a zone of my image.
Using bones... how can I move them forward or backwards to create the effect of grow/shrink?
Currently I only can move bones up/down/left/right
how to move a bone forward/backward?

Well, you *can* scale your bones -- under the right circumstances this can look exactly like moving the object forward or backward.
Only drawback in AS is the scale only works lengthwise, so if your object you're scaling needs width as well you'll have to define another bone for this purpose (not a big deal, just something to consider).

The scaling trick might work well with vectors but it isn't going to look as nice with image warping.
Bones don't have a z axis of movement as Mkelly said. And the bone scaling is only one way. There is a cool trick of using 4 bones in a "cross" shape. The base at the center pointing out like a compass.
3 of the bones uses a scale constraint to one. Scale that one bone and all the bones scale the same way creating a uniform scale effect. Set the bone strength for all the bones so the overlap uniformly and the effect is very good. Some here have used this for scaling eyeballs with bones.
This might work with an image... but you would want to test it out to be sure. I find image warping isn't as fluid as you want for extreme manipulations.
