css custom cursor not working

Question

I am using the css custom cursor to use an image for the cursor. The image doesn't work. What is wrong with this code?
Here is the image used. Fiddle

 cursor: url('http://www.sarkelliancreed.comule.com/pics/TREES.jpg'), auto;

I was dealing with this problem last night. The issue is that there is a limit to the size of the image you can use as a cursor. If you really need an image that large to follow the cursor, have a div with that image snap to the cursor position on the mousemove event.

MDN at least describes the size limit for Firefox:

In Gecko (Firefox) the limit of the cursor size is 128×128px. Larger cursor images are ignored. However, you should limit yourself to the size 32×32 for maximum compatibility with operating systems and platforms.

Put in this smiley rather than the image you're using as the URL and run the Fiddle again, and it works: http://icons-search.com/img/icons-land/IconsLandVistaStyleEmoticonsDemo.zip/IconsLandVistaStyleEmoticonsDemo-ICO-Cool.ico-32x32.png
