Added. I wish the wiki had emotes, there'd be thumbs up here.
I unfortunately had to screengrab to have a workable file (images in these sort of posts always turn into useless WebP files for me if I try to save them directly). If you want to update the image, all you have to do is go to the image's URL, go to the File History section, and click on the link at the bottom of that section that says "Upload a new version of this file." It'll automatically update on the Enbian page, too.
Your flag's URL: https://lgbta.wikia.org/wiki/File:Foxesforever_Enbian_flag.png
(Also quick side note: I always mark every flag I upload as covered by copyright and being used in a fair use way. I got that from zine culture, where you treat even an eight-pager as your intellectual property, because, well, it is. These are our flags that we're choosing to share on the wiki, and it sets that expectation that all of our flags are used respectfully. Tangent over.)
