Yes, you can probably see the image because you are set up with that website with a screen name or something, but not everyone is. Please defer to a universal host such as
xs.to or
imageshack.us , so as to ensure that the members of the board can see these images, and once the image is hosted on those sites or even on the current one, please take the url of the image, not a php/javascript/what have you handle. You will know when you have gotten the proper image url when it ends in an image file extension (like myimage.png, otherimage.jpg, etc)
