This is a reminder to stop image warring with other users, as you have been edit warring with image uploads. On most wikis, the "Replace" option for a picture is used to upload a better version of the same picture. For example, one that is less blurry or a higher-resolution version.
If you want to change the picture to something completely different, it needs to be uploaded as a new picture. To do that, go up to the "Contribute" button in the upper right corner of any page and click on the triangle in the button, then select "Add a photo". That way, the original picture is still available for someone else to use.
Also we have no way of knowing whether or not you really did create those images that you've been image warring over. Unless you can figure out some way of proving that you really did create those images, it is in our best interests to keep those images on the wiki, the way they are.
