No, it was 2-3 images at most. I use the commons app in the field to take a picture, and add wikimedia_commons link to it directly (via EveryDoor or OsmAnd), so waiting until I get to the computer is not really an option (well I could be just leaving notes with pictures via SC I guess, but then it is too much work back home to solve all of them). If you can reliably reproduce the upload bug, it would be great to add info to that issue tracker!
