If I use that picture from my site ı bloke my own site or my site shutting down
On your own wiki, it's really a grey area. Some DeviantArt artists don't like their images used on other websites, and you should at least ask those artists first. There are also artists that like their image to be credited, and there are artists whose images you can freely use. My advise here would be to ask the creator of the images you want to use for permission.
And one more question, if they are used without permission, do they know if the system shuts down?
The system will not shut down, but if a claim is made, the image might get deleted.
Ok 👌
A good general guideline is this: if the wiki is meant to promote a topic, then images used based on that topic usually fall under "fair use".
However, it sounds like you want to use a Ben 10 image on a wiki that is not specifically about Ben 10, so generally that is not allowed.
However, unless the wiki gets big, most copyright holders won't waste the time issuing a take down notice.
