To get started you need to input an Image Location into this box. A URL for any image can be found by right-clicking on it and choosing Properties from the dropdown menu. A properties box should pop-up, here you will find Address (URL):. Copy the URL displayed to the right of this and paste into the box here at addglitter.com.
The above image shows an example when trying to get the properties of the Google logo. Any image you find must end in .jpg, .gif or .png to work
You should be hosting the image yourself when using addglitter.com. There are plenty of free image hosting services out there. Please do not hotlink images.
