I've blocked you for a month now, because you've added a photo that does not relate to the Cars franchise, and put it onto a few of the articles even though it's not supposed to. If you do that again, you will be blocked for a longer period.
Please do not call other users jerks. Also I find the claim "My computer had a freaking glitch in it!" utterly unconvincing. That does not explain how you somehow managed to upload it here, or add it to other articles, without meaning to. You will need to patiently wait your block out.
I work with computers so let me try explain what the glitch would have to do to do what you did. It would have to get downloaded or created and then be programed to open your web browser then open THIS spicific wikia and then log in with the credentials you have for your account, find the media upload button, find the file, upload the file, then go to 3 spicific articals and delete pictures then add them to the page and add some text with it. Thats one very spicific Virus don't you think?
As per our new block policy, you have been blocked for one week for adding unsourced information to character articles. I already left a reminder message in the past about this, plus I have explained plenty of times in edit summaries and elsewhere that Wikipedia is not a valid source unless it points to an official one.
When adding new information about upcoming/recently released products, like Cars 3, you need to provide a source along with it. I've yet to find anything that calls that red racer "Ember Ross". If you know of somewhere that does, then you need to state the source.
