I tried to upload a photo on a computer yesterday that I took yesterday with no success. This morning I tried to upload it again from two different computers, again with no success. I then tried a different photo from the same group I took yesterday, no luck. So I tried a photo I had taken ten days ago and it uploaded. Next I tried the original photo I had wanted to upload yesterday, still no luck. Do they need to age like cheese or wine or what? :)
