Wikipedia:Picture of the day/Unused

This is a page of featured pictures that have been skipped from appearing as picture of the day for various reasons. Some of these are mainly blocked by their articles or usage (for example, a very short article, or insufficient context), whereas others have more fundamental problems and will probably never appear on the main page. This is not a policy page or archive of discussions; with the exception of the first category, things may be removed from here without any further discussion. Note that some headings may be empty at any particular time. This is fine, it's better to have a framework for new images to be added to than to lack that framework.

Pictures added to this page should also be manually added to Category:Picture of the day/Unused.

For pictures that have not appeared yet, see Category:Featured pictures that have not appeared on the Main Page.

Least likely to appear
Major problems or cases where we simply did not act in a timely enough manner, and Wikipedia has moved on from the images too much. Largely a mixture of "We can't put that on the main page!" and "...Should this still be a featured picture?"

Could cause harm
THESE MUST NOT APPEAR WITHOUT FURTHER DISCUSSION

Licensing issues
Non-free material must not appear on the main page. As such, anything with unclear status cannot appear.

Probably not actually a featured picture anymore
Images with no significant usage, and unlikely to gain any, or just really bad quality. These should probably be delisted.

Ones primarily blocked by articles
There's nothing inherently wrong with these images, but their articles are either too short or too problematic to put on the main page. If someone was willing to put in the work, most of these are potentially main page worthy.

Doubts as to whether this is the preferred version
Images that may or may not have some usage, but have another version of some prominence that should probably be talked about before we put this on the main page.

Holding areas
These images may be about to leave POTD/Unused, by one means or another. Things are unlikely to stay in these categories all that long, so they might be empty at any one time, but should be kept around to encourage proper classification.

Under discussion
These images are temporarily being delayed to allow a discussion or delist vote to take place.

Potentially ready for Main Page?
Images held back at one point, but which might be fine now. If they are obviously fine, just remove Category:Picture of the day/Unused from the image, and it should be scheduled shortly (possibly by you).
