One if you are uploading from your computer, you choose a file and upload it.
One to enter a URL if you have already uploaded it somewhere, this should accept a direct URL for example from Imgur that ends in .jpg or .png
The URL Empty is a message I recently added to try and debug why some URLs werent accepted.
