That's pretty easy.I am not an expert in making meshes, but i know a little.So, first you download a picture (preferrably .png) and save it in: FH folder -> Media -> Textures (You will see that in the 'textures' folder are alot of pictures that look like...some textures, indeed xD) So, after you save it there, you go on FH, and then to object maker.You select any object outta there, and put the texture file name (e.g.: texture.png, MUST have '.png' at the end!) and, the object will appear with the texture on.I personally tried this also, and i've created a zebra with an I.T texture c:.It will sure work, if you know how to do it!
Hope this helped you!
