You are having a serious duplicate files uploading issue :0
You have uploaded 52 files that already existed on the wiki. 52!
Please take in mind that this wikia is not a file host, and make sure you don't upload the same images twice. Using Special:Upload might help, since it warns when you try to upload an image that already exists, and gives you a link to that file.
Here is an example of what happens when you use Special:Upload or Special:Images to upload new files to the wiki. I tried to upload the file that already exists, but with a different name, so it warned me and gave the name of the same file that is already uploaded.
