Images without license or source information: The goal is to go through all images that have been marked with “no source since” or “no license” tags for more than seven days. Some images have the required information (it may have been added without removing deletion tag) and you will have to be careful not to delete those. For making things easier, use Magnus' Bad Old Ones tool. Please note that:

• Most chemical formulas can be tagged as {{PD-ineligible}}.
• Some insignia are ineligible for copyright, see Commons:Insignia.
• Images with {{PD-old}} or {{PD-art}} have to have a date or other such source information if it's not obvious that the work is indeed old.
• If in doubt, don't delete but let other people have a look.
• Be ware of derivative works.

Tips:

• In Opera, you can use “View → Fit to window width” if the page at Bad Old Ones grows too wide.
