As part of a remix competition with Kiwistar, submitted tracks must have specific artwork (https://www.dropbox.com/s/edm6b0qtfcjrh4s/Swing%20as%20Fck.jpg?dl=0
). On my track (https://soundcloud.com/anno-861/kiwistar-x-josh-le-chat-feat-flechette-swing-as-fk-anno-remix
) I can hit the 'Edit' button, select the image and click save changes, but after a while a message appears in the corner stating "Error uploading image". I have also tried the Change Image button, however when 'Save' is clicked, it turns grey as if loading something and does nothing else. I'm using Safari 7.1.2 with OSX 10.9.5.
