This is what I was talking about in Thread:96911. You can go to Special:Images, which has an upload button in the top-right that takes you to Special:Upload, and you can upload images there. Then you can go to the article, edit it in source mode, and add the file names to the gallery as you desire. This way, you don't have to add each individual image in separate edits especially thanks to the preview option.
