While I do have the ability to change it to a direct link as a default I probably wont. People can easily access the image directly from the viewer page, but not vice versa. Also from the image page or the direct page the process doesn't change for submitting a direct link. The user can right click on the picture and copy image location and the paste that into voat, nothing is really different if they intend to upload a direct link but it removes a significant number of options for those who dont.
