My Javascript Code doesnt work outside of JSFiddle
Question
For some weird reason my code will load and work in JSFiddle, however it will not work when I try using it outside of JSFiddle. Does anyone know a fix? Or what is happening? Link to the JSFiddle... http://jsfiddle.net/56yK9/12/
If you go onto the jsfiddle link click "run" after the page has loaded.

In your html document imageWidth and imageHeight equal 0, because the rest of the other functions/code doesnt wait until the image loaded from the site, (check it in your developer tool -> network) thats the problem here, so the sprite is invisible..your code might need changes..
var texture = THREE.ImageUtils.loadTexture(tUrl, {}, callback);
callback = function(texture){
........code ur stuff here...........
}
just go through the code in the link it will give you some idea on image/texture loading... https://stackoverflow.com/a/21277768/2089677

I guess you are missing an on page load / ready handler.
This little example seems to at least display something:

You can take a look at a much cleaner output of your jsfiddle creation here:
