Basically you will use a texture map only to have particles influenced in some way by an image, basically the same as a texture projection but for particle purposes, and maybe hair, not really sure on this one since Iīm not at work and canīt check it out Iīve used the transfer map function in hair before but canīt remember if you need to apply a texture map before, think not but my memory is playing around with me right now :scream:
Hope this helps...

A texture map is a property attached to the object, that holds a texture. Like chesterjoe pointed out, this texture can then be used to drive various effects, like particle emission, hair density, and can even be brought to the render tree via an Image_lookup node. On the other hand, without a texture map, you can't use any clip outside the Render Tree.

A texture projection is a specification telling the renderer (wether mental ray or ogl display) how to apply the texture on the object. Since a texture is 2D object mappend onto a 3D object, you have to tell how you want the texture to be placed onto that 3D object. Projections are basic ways to define that placement.
