A parameter like &returnto=URL could be added to UploadWizard so that the user, when upload is completed, is redirected to that URL, or even to the edit window.
For instance, https://commons.wikimedia.org/wiki/Special:UploadWizard?returnto=https://it.wikipedia.org/wiki/I._liga could link https://it.wikipedia.org/w/index.php?title=I._liga&action=submit prefilled with the current of the page, prepended with the image markup like [[File:Example.jpg|Example description]].
**User story**: Like mentioned in bug 33234 it is easy for the a potential upload to find the wizard, but often he won't be able to include his picture to the article.
I suggested at different approach here: http://commons.wikimedia.org/w/index.php?title=Commons%3AVillage_pump&diff=92525244&oldid=92523839
What about some additional get parameters like project, language and page/article when you link to upload wizard from an article?
This would offer a lot of potential workflow improvement:
1. You could use those parameters to create a link to the article the user called upload wizard from. You could write: "Now insert [[:File:.....|thumb|....]] to this article.
2. You could even link to editing the article and inserting the file source code (maybe by asking him the paragraph he wants to insert the image at?)
A different handling for infoboxes would be great, since there are a lot of infoboxes, that use the image as parameter.
