Uploaded earlier today. Did not notice it to be slow. Perhaps the high traffic is slowing down the server at the time you were uploading?
Also, what is your connection-like? Upload speeds can be highly dependent on a persons connection type as some providers have terrible upload speeds but good download speeds.
Additionally, I thank you for putting the photos in the correct category. It was the first thing I looked for when I opened the thread, lol. Private gallery would have been used in a perfect world, but alas, you did much better than many have!
