OK, easy. In the material editor, colours channel, check "mapped picture" instead of the default "procedural colors". Now there is a black square instaed of the mat sphere. Click the little arrow right at the bottom of the square, and browse for your texture on your HD. The little arrows on the bottom right are here if you want to rotate your image. The little black & white button on the top right makes your image a negative of the original ( sometimes useful for transmaps).

In the same colors tab, on the far right you can change the mapping mode of your image ( if you want to map a sphere, and the "automatic" mode, chosen by default by Vue, looks wrong, check "spherical", you get the idea.)

Now if you want to apply a texture map for bump, go to the bump tab, right click the sphere and choose edit, or silply control click. You land in the function editor. With the word "bump" higlighted, click the 6th icon from the bottom left, and your bump channel is connected to a texture map. Browse for the image you want to use as a bump map, or just connect the bump to the color channel if you don't have a bump map corresponding to your color texture map. Simply drag the little arrow that sticks from the word bump onto the color texture map.
