I just implemented the upload feature to my own editor (nothing special, something similar to Github Text Editor). After the user dropped the file to the textarea the uploading process starts and puts a returned link back to the editor:
The questions is — why the hell the links are so long?! What's the point?
First, there is a limited amount of chars in the editor. Second, it just looks ugly. And if I add ten pictures in a row it's getting even much uglier.
