From Halopedia, the Halo wiki
Thank you for your earlier message about images. I am trying to upload higher quality versions of the ones I have already uploaded, but for some reason the image does not seem to change for me. May I be doing something wrong, or might this be a browser not updating issue? Thank you for your help.
Hey dude, you've recently uploaded a bunch of really cool Halo Wars images that I've never seen before. I'd be really interested to know where you found them as they oddly haven't appeared to have surfaced for ten years, so if you have the time to share I'd appreciate that.
Don't take this the wrong way, but you should probably stop with the uploads until you're sure it doesn't already exist on the wiki. For example, the HW2 Blitz Card images already exist here, and some images from ArtStation have also been uploaded by myself (mostly weapons, vehicles to name some). If you need to check, you can check my galleries to make sure.
