How can I see a texture on my model? I made a model and I'm trying to add color to it, but for some reason the colored texture doesn't show on the model. I can't see any difference in the model. These are the steps I followed:


I unwrapped the model.
I made a blank image of the model and I baked it with 'bake mode: ambient occlusion'.
I created two .PNG files: one of the already made 'ambient occlusion' and another one of UV layout to work with them in Photoshop. 
I copied the 'ambient occlusion' image to the 'UV' image as a second layer and I just added some color to see if it shows color in the preview of the model in Blender, but it doesn't.


This is my model (the viewport is in 'texture' mode):



Maybe I have not followed the right steps, or I've overlooked something. I'd appreciate any idea of how to solve it. Thanks!
To add an image texture to your model you need to follow these steps (There might be other ways, by the way; but this is the way that i would do it):


UV Unwrap your model
Add a new material to it




Add your image texture to the material





And you should be good to go
