Dear all, I plan to redesign it, I will tell you guys the plan and give you the scratch a few days later. But I don't know how to apply the changes, so hope some one may teach me.
Thanks for your interest. UploadWizard uses (or should use if it doesn't) mediawiki.feedback.js, so that's the file you're looking for. Its most prominent advocate is James Forrester, bug him if you have questions. :D Some ideas for improvement can be found in bugzilla: https://bugzilla.wikimedia.org/buglist.cgi?list_id=287921&longdesc=mediawiki.feedback.js%20&longdesc_type=allwordssubstr&product=MediaWiki&query_format=advanced&resolution=---.
