A required field in the upload page for source information is an excellent idea. I would not carry it so far as to subject images without source information to speedy deletion, at least not in the sense that is practiced on en.wikipedia. Such images should go on VfD if there is concern about the use, to allow time for us to track down the actual source and investigate whether we can still use the image.
To give a source take 30 seconds on the part of the uploader. To go through a VFD procedure for a single message can take hours for other wikipedians. It's as much as matter of courtesy as fixing links when you make a disambiguation page.
