Using planes as 2D characters in an 3D animation (help!)

I’m not sure if this is posted in the correct place, but please move it if it isn’t.

I’m a blender newbie, and I’m aiming to create a very, very simple animation. There’ just few things that I’d like to ask.

I’m not quite sure how to explain my idea, but I’ll try: I have been toying around with the idea that I would create a 3D animation with 2D characters, like placing paper dolls on a 3D scene. I would draw (for example) the silhouette of a character, and place it on a square plane in Blender. The problem is I dont know how to remove the excess that is left over the silhouette, the grey plane. I’ve already gotten a bit into the basics of blender, but I’d like to know if there is a tutorial for this kind of thing? Or is it even possible?

Just to explain it as specifically I can: The easiest way that comes to my mind with this, is that you make a plane, then add the texture to the plane. If you add a human character silhouette image on square plane, there will be empty plane left with no texture. So I would need to remove that, so that plane would be shaped as the silhouette of the character, so that things behind it would show properly. But I do not know how to do that.

Any help would be appreciated!
If there is a easier and more logical way to do this please enligthen me! :o

There are 3D elements that I plan to use on this (like lighting etc), so that is why I would use a 3D modelling program to start my project.

Thank you for your help!

Set the background of the image to be transparent then add the texture to your plane, enable Transparency, set the alpha to zero, set the texture to influence both Color and Alpha
