User William Alken uploaded an image to the Series 1 List, and also coldposted an SCP that doesn't seem to have anything to do with the image. (the coldpost is here)
I've sent him a PM:
Hi there,
I'm Zyn, a moderator on the SCP wiki.
It's been noticed that you uploaded an image to the files associated with the SCP Series list (the page is here). If you want to have an image hosted on the site, please do so either on a sandbox page that belongs to you or the actual article page that the image will be used on. Generally images are not supposed to be hosted on the Series 1 or Series 2 lists, and there's a chance that another staff member may remove the image as part of site maintenance.
If you have any further questions, feel free to PM me or another staff member.
Regards,
Zyn
Edit: Having not gotten a reply from the guy, I've moved the image to the guy's sandbox and taken it off the Series 1 list.
