I'm not sure how to appropriately contribute this image. If anyone can direct me where I should go with this, or bring this thread to the attention of a member who can make edits, then problem solved! Thanks!
That wiki may or may not require you to be autoconfirmed (i.e. account is 96 hours old). If you try and it doesn't work, then you probably need to be autoconfirmed. You can upload a new version of the image by going here, clicking the down arrown next to "Edit", and then clicking "Replace" in the dropdown menu.
