William,
Quoting William Pietri william@scissor.com:
The 7 days here or 5 for proposed article deletion seems like a reasonable balance between friendliness and tidiness, but I'd be a little frustrated to find that something I was working on was gone because I'd taken the weekend off.
You're clear that we're discussing uploads of unusable unfreely licensed media here, right? Nobody's suggesting that the free content work of Wikipedia contributors be deleted more quickly.
