I am watching a tutorial on how to UV map a model and I have this horse I created. There should be a section named 'Surface' beneath the section named 'Preview' which is required to select the image. I have tried restarting blender and it just isn't there. I really hope that I don't have to re install blender.
Once you've created a material go to the texture section, and create a new texture ->image. The texture will now be associated with the material.
Open the image you want to use and then you need to assign some coordinates for the texture mapping and what kind of influence the texture is going to have on the material, the default is Color.
