Not showing texture after uv maping and importing png image? I am just learning blender..I made a 3d character and unwrapped it.. But when I opened the image in UV editing window it didn't show the any texture.

I had to reload your image texture from disk to get it to show up. Once I did that I just changed the viewport mode from Solid to Textured and the textures appeared.
